Abstract: 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.

Abstract: 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.

Abstract: When an engine speed is less than a safeguard speed while a vehicle downhill assist control is being executed, a target speed of the vehicle downhill assist control is increased. In addition, if the target speed is greater than a vehicle speed, braking force applied to the vehicle is decreased.

Abstract: 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.

Abstract: 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.
Abstract translation: 当电动机的驱动打开并且低压侧车轮的W / C压力增加时，马达的驱动继续进行直到同一系统中的高压侧车轮的实际W / C压力达到 相对于目标压力的预定范围。 具体地说，如果低压侧轮的目标压力大于预定值，则低压侧车轮的制动液压增加，电动机被驱动，并且由此导致 高压侧轮的W / C压力继续驱动马达，直到高压侧轮的W / C压力恢复。 从而可以防止马达的温度上升，并且尽可能地缩短马达的驱动时间可以提高耐久性。
