Abstract
In a braking-force distribution control system for a vehicle, which is capable of controlling the ratio of a braking liquid pressure for front wheels to a braking liquid pressure for rear wheels based on a comparison of front and rear wheel speeds, a correcting factor is calculated in a correcting factor calculating device based on the ratio of front and rear wheel rotational speeds detected by front and rear wheel rotational speed sensors. At least one of front and rear wheel speeds, calculated in front and rear wheel speed calculating devices, is corrected by a wheel speed correcting device prior to the calculation of a control quantity in a control quantity calculating device. A control determining device determines whether the range of variation in correcting factor is equal to or larger than a preset value. When the range of variation in correcting factor is equal to or larger than the preset value, a signal indicative of a command to prohibit the calculation of the control quantity based on the result of the comparison of the front and rear wheel speeds in the control quantity calculating device is output from the control determining device. Thus, it is possible to perform an…
