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: 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.
