Abstract
An electric park brake control (,) for a parking brake actuator (,) selectively operates a brake mechanism (,) at at least one wheel to selectively perform a parking brake function. Inputs to the electric park brake control include an input from a shifter (,) for distinguishing PARK position from other positions. The electric park brake control causes the brake mechanism to perform the parking brake function when the input from the shifter to the electric park brake control discloses that the shifter is in PARK position. The electric parking brakes are integrated with the shifter, eliminating a parking pawl from a motor (,) that propels the vehicle. Neither is an operating cable from the shifter to the motor for operating the parking pawl required. The shifter is coupled in exclusively electrical relationship to a traction inverter module (,) for causing the motor to operate in correspondence with the particular position selected by the shifter. A security controller (,) causes the electric park brake control to apply the parking brake when a security violation is detected.
