A road surface condition detecting and anti-skid controlling device in a car capable of detecting the road surface condition with high accuracy in a multiple-step manner, so that brake pressure control and attenuating capacity adjustment of shock absorbers as well as car level adjustment are more effectively executed. The invention is includes: car wheel speed and car speed detecting devices, a speed changing rate detecting device, memory, valve, calculating, integrating, and comparing devices, and a brake pressure control device. According to the invention, the road surface condition is detected with high accuracy and anti-skid control is more effectively executed by pertinent brake pressure control in response to the road condition so that a high degree of safety and reliability for the brake control in car can be obtained.
