TRW's Electric Park Brake (EPB) enhances vehicle safety, driver comfort, convenience and allows for greater freedom of vehicle interior design and packaging. In addition to providing parking brake functionality, EPB is a fully integral part of the brake system that also allows for emergency brake control. When combined with TRW's Electronic Stability Control (ESC) system, emergency braking is executed through the Vehicle Stability Control (VSC) unit on both axles allowing for full four-wheel ABS stop functionality if required. In a standard park brake system, only the rear axle of the vehicle brakes during an emergency event. EPB also eliminates the need for a parking brake control mechanism inside the vehicle. This results in enhanced ergonomics, improved vehicle styling, and improved space management The EPB system's communication interface with onboard computer systems means that a number of design features can be added or deleted as specified for the application. Among the many features that can be offered are: Drive away assist – upon acceleration of the vehicle, the park brake releases •Hill Hold – prevents vehicle rollback on a hill until the driver accelerates Manual release - only when the brake pedal is pressed Brake wear sensing  - brake pad wear monitoring to signal the driver of worn pads Interface between the EPB switch and accelerator pedal – prevents false-apply Automatic parking brake apply when driver’s door is opened •
