BMW 3: Introduction
BMW 3 Series G20 (2018-2025) Training manual / Hybrid Brake System / Introduction
The function of the brake system of the G20 PHEV is to decelerate the vehicle safely under stable conditions. Vehicle deceleration is made up of the following elements:
- Conventional hydraulic braking
- Regenerative braking
Thanks to regenerative braking it is possible to convert the kinetic energy of the vehicle into electrical energy with the help of the electrical machine, and to therefore charge the high-voltage battery unit.
The service brake of the G20 PHEV is based on that of a conventional G20. In this chapter only the hybrid-specific components and functions are described.
In comparison to the conventional G20, the following new or modified components are used:
- Brake pedal travel sensor
- Brake vacuum pressure sensor
- Modified vacuum brake system
- Modified DSC unit
