Abstract: A brake ECU of a vehicle braking control device, during execution of brake pressurization control, performs actuation restriction control that restricts actuation of a motor as an arbitrary upstream fluid pressure (M/C pressure) that is the brake pressure input from the M/C side of the brake fluid pressure control actuator becomes higher. The brake ECU has a threshold value changing unit that sets at least the starting threshold value at a high level when the upstream fluid pressure (M/C pressure) is high compared to when low, and as actuation restriction control actuates the motor to pump out the brake fluid from inside of the reservoirs when the reservoir fluid volume exceeds the starting threshold value, and stops the motor when the reservoir fluid volume equals the stop threshold value.

Abstract: A vehicle control device corrects the amount of brake control according to the degree of stall prevention requests such that the brake control amount is matched to a travel state. For example, when the vehicle body speed is low, the vehicle body is often traveling a road surface that is difficult to travel, and the degree of stall prevention requests is small. In such cases, the vehicle control device exhibits LSD effects and increases ground-covering properties by executing vehicle wheel slip control based on stronger brake control, while increasing safety properties by better enabling generation of deceleration. Then, as the vehicle body speed increases, because it is conceivable that the vehicle body is leaving a place that is difficult to travel and the degree of stall prevention requests is high, the vehicle control device executes switching such that brake control is lowered.

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 translation: 为了牵引控制，分别提供了不同的过滤器，即液压增压过滤器和液压减压过滤器，用于增加和减小目标压力。 相对于目标压力变化而言，液压增压过滤器显示的抑制效果小于液压降压过滤器相对于目标压力的变化而显示的抑制效果，因此目标压力增加 迅速但缓慢下降。 因此，即使在实际的车轮缸压力随着目标压力增加之后车轮气缸压力降低，轮缸压力也逐渐减小，从而减少了达到目标压力所需的压力增加量 轮缸压力接下来增加。 因此，轮缸压力可以充分提高以达到目标压力高度的响应性，从而可以防止由于低加压性能而不能精确地提高轮缸压力。

Abstract: This vehicle brake device comprises: a simultaneous driving determination section which determines whether it is necessary to simultaneously drive an upstream-side motor and a downstream-side motor; and a PWM control section which, when the determination result by the simultaneous driving determination section is in the affirmative, changes the duty ratio of the PWM signal to be output to the upstream-side motor so as to be smaller than when the determination result by the simultaneous driving determination section is in the negative, and uses PWM control to drive the upstream-side motor.

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: 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.
