The invention discloses a wheel cylinder hydraulic pressure control method based on a mechanical electronic hydraulic brake system. The wheel cylinder hydraulic pressure control method comprises the following steps: selecting different brake modes according to the difference of brake working conditions; building pressure according to motor output by a main cylinder under a conventional brake working condition, and maintaining the hydraulic pressure of each wheel cylinder to be the same as that of the main cylinder; under an emergency working condition that different hydraulic pressures are required for the wheel cylinders, generating constantly fluctuant hydraulic pressures in the main cylinder by the motor to meet different hydraulic pressure requirements in the wheel cylinders, thus using electromagnetic valves to realize the functions such as anti-lock brake or electronic stability control. The method disclosed by the invention cancels eight electromagnetic valves for realizing an ABS (Anti-lock Brake System) or twelve electromagnetic valves for realizing an ESC (Electronic Stability Control system) in a traditional brake system, corresponding functions can be realized by using only four electromagnetic valves, and the method is high in control precision, safe and reliable and has a good control effect.
