Abstract

An execution device 62 of a driving assistance device 60 derives a reference drive force, which is a drive force required to increase the vehicle speed of a vehicle 10 to at least a target vehicle speed, on the basis of the gradient of a road surface on which the vehicle 10 is positioned and/or the weight of the vehicle 10. From the time at which the vehicle 10 is stopped, the execution device 62 starts a holding control by which a drive force instruction value is held at the reference drive force, and when the vehicle 10 does not start by executing the holding control, the execution device ends the holding control and increases the drive force instruction value beyond the reference drive force. When the vehicle 10 is traveling, the execution device 62 adjusts a braking force instruction value by a feedback control which is based on the deviation between the vehicle speed and the target vehicle speed.

Abstract

This motor control device comprises: a control unit that executes sensorless control on a brushless motor BM having three phases; and a determination unit that determines the presence or absence of stepping-out of the brushless motor. The control unit executes sensorless control on the basis of an estimated d-axis output current Ids, an estimated q-axis output current Iqs, an estimated d-axis instruction voltage Vdc, an estimated q-axis instruction voltage Vqc, and an estimated rotation speed ωs. The determination unit calculates a determination voltage Vqj on the basis of the estimated d-axis output current Ids, the estimated q-axis output current Iqs, and the estimated rotation speed ωs. When voltage deviation hV, which is the difference between the determination voltage Vqj and the estimated q-axis instruction voltage Vqc, exceeds a determination threshold value Hs, stepping-out is determined to have occurred. For example, the determination unit decides the determination threshold value Hs to be larger as the estimated rotation speed ωs increases.

Abstract

A current command value deriving unit of a motor control device derives a d-axis current command value and a q-axis current command value based on a torque current map and a torque command value. A voltage command value deriving unit executes a first process of deriving a d-axis voltage command value based on the d-axis current command value and deriving a q-axis voltage command value based on q-axis current command value, and a second process of deriving the d-axis voltage command value based on the q-axis current command value and deriving the q-axis voltage command value based on a limit voltage and the d-axis voltage command value. When a motor is driven by field-weakening control, the voltage command value deriving unit switches from the second process to the first process when it is determined that the voltage command value satisfying the torque command value is derivable by the first process.

The sensing bodying sensing an axial position of the master piston without relative movement, that is, without providing play. This arrangement improves the sensing precision of the sensing device. Since it is not necessary to provide a member separate from the master piston in order to retain the body to be sensed, it is possible to achieve downsizing of the brake fluid pressure control apparatus.

Abstract

Example ultra narrow linewidth Brillouin lasers are disclosed that are pumped by pump lasers that are controlled via optimal control schemes in order to stabilize the Brillouin laser output frequency and minimize the Brillouin output linewidth. The control schemes are based on feedback loops to match the pump laser frequency to the optimum Stokes shift on the one hand and to line-narrow the pump laser linewidth on the other hand via comparing the linewidth of the pump laser with the linewidth of the Brillouin laser. The feedback loops in the control schemes can be partially or fully replaced with feedforward control schemes, allowing for larger bandwidth control. Provision for simultaneous oscillation of the Brillouin lasers on two polarization modes allows for further line-narrowing of the Brillouin output. The ultra-narrow linewidth Brillouin lasers can be advantageously implemented as pumps for microresonator based frequency combs, and can also be integrated to the chip scale and be constructed with minimal vibration sensitivity. The ultra-narrow linewidth Brillouin lasers can be widely tuned and a frequency readout can be provided via the use of a frequency comb. When phase locking a frequency comb to the Brillouin laser, ultra-stable microwave generation can be facilitated.

Abstract

A brake fluid pressure supply unit includes a fluid pressure generation device in which a piston that slides in a cylinder is driven by an electric motor to generate fluid pressure in a fluid pressure chamber formed in the cylinder; and a housing in which a fluid path connected to the fluid pressure chamber is formed. The electric motor and the cylinder are both attached to the housing. The electric motor is positioned more on upper side of the brake fluid pressure supply unit than the cylinder in a vertical direction. Thus, even if fluid leaks from the cylinder, the fluid having leaked can be prevented from entering inside of the electric motor. Thus, the operation of the electric motor is not impaired, whereby the reliability of the brake fluid pressure supply unit can be improved.

Abstract

A braking control device executes pre-stop braking control to adjust a braking force when a vehicle stops. The pre-stop braking control includes reduction control that reduces the braking force, and increase control that is executed before the reduction control is started, to increase the braking force. An increasing unit executes the increase control, and a reducing unit executes the reduction control. A calculation unit calculates a braking distance extended by the reduction control, as an extended distance, and calculates a braking distance shortened by the increase control, as a shortened distance. The calculation unit calculates the extended distance to become longer when an operation amount of a braking operation member operated by a driver is reduced during braking than when the operation amount is not reduced. When a difference between the extended distance and the shortened distance is less than a determination value, the reducing unit starts the reduction control.

Abstract

This vehicle braking control device comprises: an application unit having a servo chamber and a supply chamber sealed by a seal member; a pressure adjustment unit that adjusts a front-wheel wheel pressure by supplying a first servo pressure to the servo chamber and outputting a front-wheel supply pressure from the supply chamber to the front-wheel wheel cylinder, and that adjusts a rear-wheel wheel pressure by outputting a second servo pressure as a rear-wheel supply pressure to a rear-wheel wheel cylinder; a front-wheel/rear-wheel supply pressure sensor that detects a front-wheel/rear-wheel supply pressure; and a controller that selects either a two-system pressure adjustment in which the first and second servo pressures are adjusted individually or a one-system pressure adjustment in which the first and second servo pressures are made identical. For the two-system pressure adjustment, the controller individually calculates a target pressure for the front wheel and for the rear wheel, and causes the front-wheel supply pressure and the rear-wheel supply pressure to match the front-wheel target pressure and the rear-wheel target pressure. For the one-system pressure adjustment, the controller equalizes the front-wheel and rear-wheel target pressures and adds a prescribed pressure thereto to calculate a common target pressure, and causes the rear-wheel supply pressure to match the common target pressure.

Abstract

A vehicle includes a sideslip preventing function of preventing a sideslip of the vehicle by separately adjusting a longitudinal force applied to each of the wheels. A controller controls the vehicle based on requests input from a driver assistance device, thereby causing the vehicle to travel autonomously. The controller calculates wheel lateral force request values based on the requests input from the driver assistance device. The wheel lateral force request values are request values of lateral forces acting on the respective wheels. The controller, when a behavior of the vehicle is in an oversteer state in a case in which the sideslip preventing function is failing, limits the wheel lateral force request values for the front wheels to values less than or equal to a first lateral force limit value, which is a limit value of the lateral force that can act on the rear wheels.

Abstract

A control device includes an electric motor, a battery, a capacitor, a power source selection portion, a determination unit configured to determine whether the battery is normal, and a control unit configured to select, as a control mode of the electric motor, one of a first mode and a second mode in which a power consumption amount of the electric motor is reduced as compared to when the electric motor is driven in the first mode, and drive the electric motor in the selected control mode. When the battery is transitioned from a state of being determined to be normal to a state of being determined to be not normal, the control unit switches the control mode from the first mode to the second mode and then makes the power source selection portion select the capacitor.
