The integration of these two functions within one harness has become possible as a consequence of the electrification of ancillary components, with electric parking brake being a clear trend in new vehicle designs, Continental explained. The company said there is a strong and quickly growing demand for EPBs. There are several benefits: In connection with electronic brakes, EPBs can be integrated into several driver assistance functions such as hill holder or automatic emergency stop in the case the service brake fails. In addition, the elimination of the clumsy brake lever offers new options for interiors designers.
OEMs expect the EPB to become fully integrated into the brake system in the future, Continental said. In addition, the common cable harness for EPB and wheel speed sensors will over time be integrated into the rear axle.
The data provided by the wheel axle speed sensor are utilized by indirect tire pressure monitoring systems (iTPMS) as well as by a number of driver assistance functions such as electronic brake system (EBS), anti-lock braking system (ABS), and electronic stability program (ESC).
