Abstract
A hydraulic control unit capable of being used in an automotive vehicle wheel brake system includes a pressure generator such as a master cylinder for a vehicle wheel brake system that includes automatic brake control features. Solenoid-operated valves are used to control the flow of brake fluid to and from the fluid pressure actuators for front and rear brakes. A fluid reservoir is used for storing hydraulic fluid in the hydraulic control unit. A source of electrical energy, such as a solenoid-operated valve, is used to heat the hydraulic fluid to reduce fluid viscosity and thus enhance control unit performance.
