BMW 3: 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

The brake booster is operated via the driver's foot operation, and the brake
actuation is determined by
means of the brake pedal angle sensor.
