摘要： This brake ECU executes vehicle downhill control for adjusting the braking force to be applied to a vehicle by actuating a brake actuator such that the vehicle body speed does not exceed a target speed. Also, in cases where the accelerator pedal is being operated in a state where the vehicle downhill control is being executed, the brake ECU changes the target speed such that, the longer the operation duration which is the duration for which the accelerator is operated, the higher the target speed.

摘要： In a collision avoidance control device for a vehicle according to an embodiment, for example, when receiving a brake request from a driver while a brake device is given an operational instruction corresponding to a third deceleration, a brake controller controls at least the brake device to decelerate the vehicle at a deceleration calculated by adding the third deceleration and a fourth deceleration corresponding to the brake request.

摘要： When driving of a motor is on and W/C pressure of a low-pressure-side wheel is increased, the driving of the motor is continued until the actual W/C pressure of a high-pressure-side wheel in the same system reaches a predetermined range relative to a target pressure. Specifically, if the target pressure of the low-pressure-side wheel is greater than a predetermined value, the braking hydraulic pressure of the low-pressure-side wheel is increased, the motor is driven, and to account for a resulting decrease in the W/C pressure of the high-pressure-side wheel, the driving of the motor is continued until the W/C pressure of the high-pressure-side wheel is restored. Temperature increases in the motor can thereby be prevented and durability can be improved by shortening the drive time of the motor as much as possible.

摘要： A vehicle braking system is provided with: a driving motor that can apply a regenerative braking force to a wheel; a friction braking device that is operated so as to apply a friction braking force to the wheel; and a braking control device. The braking control device controls the friction braking device on the basis of the detected value of a wheel speed when the detected value of the wheel speed of the wheel based on an output signal from each of wheel speed sensors SE5-SE8 can be acquired, and, when the detected value of the wheel speed cannot be acquired, acquires the estimated value of the wheel speed of the wheel on the basis of the rotational speed of the driving motor and controls the friction braking device on the basis of the estimated value of the wheel speed.

摘要： This driving assistance device includes a braking control unit and a target speed determination unit. The braking control unit executes driving assistance control for adjusting the braking force to be applied to a vehicle by actuating a brake actuator such that the vehicle body speed does not exceed a target speed. In cases where the accelerator pedal is being operated in a state where the braking control unit is executing the driving assistance control, the target speed determination unit determines the target speed depending on the larger value of either: the vehicle body speed that is correlated with at least one of the wheel speeds of the plurality of wheels provided to the vehicle; or the lower speed limit value that has been set.

摘要： For traction control, different filters, i.e., a hydraulic-pressure-increase filter and a hydraulic-pressure-decrease filter, are provided for increasing and decreasing target pressure, respectively. The inhibiting effect that the hydraulic-pressure-increase filter exhibits with respect to target pressure changes is made less than the inhibiting effect that the hydraulic-pressure-decrease filter exhibits with respect to changes in the target pressure, and so the target pressure is increased quickly but decreased slowly. As such, even if the wheel-cylinder pressure decreases subsequent to the actual wheel-cylinder pressure having increased to follow the target pressure, the wheel-cylinder pressure decreases only gradually, reducing the amount of pressure increase needed to reach the target pressure when the wheel-cylinder pressure is next increased. The wheel-cylinder pressure can thus be increased sufficiently to reach the target pressure with a high degree of responsiveness, making it possible to prevent being unable to increase the wheel-cylinder pressure accurately due to low pressurization performance.
