WHEN THE BEST IS JUST ABOUT GOOD ENOUGH

Full recuperation with consistent braking dynamics

During recuperation, the electric motor adds an additional braking torque to the wheels. This is compensated with a reduction of brake pressure by the brake-by-wire system. Having no restrictions on the IBSe pressure target, this results in a considerably greater degree of freedom in terms of managing recuperation. Our customers can fully exploit the vehicle’s recuperation capacity without disturbing the vehicle dynamics.

Pedal simulator provides perfect handling

Brake-by-wire systems from LSP are situated between the brake pedal and the wheel brakes. An optional pedal simulator, which is individually adjusted for each customer, ensures constant pedal feel for the driver throughout the entire race – completely independently from the recuperation strategy.

Pressure control based on target signal

The LSP system can adjust any wheel pressure in less than a tenth of a second. This means brake balance can be optimally controlled in real time. The simple and proven CAN interface is quickly installed, and the system adapts itself automatically to a new brake system or vehicle.

Unbeatable reliability and durability

All LSP brake-by-wire systems comply with the IP67 seal classification and are subjected to numerous shaker, climatic chamber, endurance and sealing tests during development, thus conforming with the highest quality standards.

Highest safety standards based on series development for passenger car brake systems

To ensure drivers are not only first to cross the finish line, but also that they do so without accident or injury, LSP uses integrated electronics with proven fail-safe routines and 100% self-diagnosis features (system status, communication, pressure-volume characteristics, leakage). The hydraulic fall-back provides additional safety, especially during integration of the system into the vehicle.

IBSe System Layout

The system has two different main operation states:

IBSe-enabled

In this mode the IBSe controls the wheel pressure based on the pressure demand coming from the vehicle control unit (VCU). The TMC is disconnected from the wheels and therefore connected with the pedal simulator. It is thus possible to control wheel pressure independently from the driver’s pedal feel. In this operating mode, overall energy recuperation for the electric motor (EM) is not restricted by the brake system.

IBSe-disabled (hydraulic fall-back mode)

In case of any system failure, the primary chamber of the TMC is directly connected with the brake calipers of the wheels. The pedal simulator is disconnected from the line. Wheel pressure is controlled by the driver, recuperation influences the drivers pedal feeling.

IBSe 7 HP System Layout

IBSe 7 HP is installed at the brake pipe between the tandem master cylinder (TMC) and the brake calipers. There is no need for a reservoir connection.
