ESP® hev

Characteristics of ESP® hev for vehicles with front axle/rear axle brake circuit distribution (II distribution)

The regenerative braking system ESP® hev has been specifically developed for hybrid and electric vehicles with front axle/rear axle brake circuit distribution (II distribution). The system enables purely generative deceleration of up to 0.2 g.

ESP® hev decouples the rear axle braking circuit from the brake pedal each time braking takes place, regardless of whether the vehicle is decelerated using a generative or hydraulic process. The system continuously conceals the braking torque on the rear axle without disruptive transitions in deceleration. The pedal feel is solely dependent on the front axle braking circuit and is similar to the feel the driver is used to in conventional vehicles.

Characteristics of ESP® hev for vehicles with front axle/rear axle brake circuit distribution (X distribution)

The regenerative braking system ESP® hev for vehicles with front axle/rear axle brake circuit distribution enable a purely generative deceleration of up to 0.2 g when combined with a conventional vacuum brake booster. If the ESP® hev is combined with an iBooster, purely generative decelerations of up to 0.3 g are possible.

ESP® hev for vehicles with front axle/rear axle brake circuit distribution is based on the ESP® plus generation 9 and the use of proven standard components. The low-pressure accumulator chamber and the valve-filter principle were modified for the use of the ESP® hev system for
