Vehicle dynamics control 2.0

Unlock the full potential of braking, chassis, steering, powertrain, and by-wire systems

With vehicle dynamics control 2.0, Bosch is tapping into the full potential of actuators of different vehicle domains and its extensive, long-standing expertise to bring vehicle dynamics to the next level. Bosch is thus delivering an extraordinary driving experience in everything from compact to premium cars and light commercial vehicles – be it in manual, assisted, or automated driving mode. Vehicle dynamics control 2.0 serves as the core control system for the latest generations of the electronic stability program ESP^® and the integrated power brake.

Vehicle dynamics control 2.0 incorporates an innovative smart control concept, which allows the function to “think ahead”. Based on the information from vehicle dynamics sensors, it anticipates the vehicle behavior and intervenes proactively – acting instead of reacting. As a result, drivers benefit from a natural driving experience characterized by excellent safety, agility, and comfort, all the while maintaining full control of the vehicle. The integrated control concept enables straightforward integration of various actuators for vehicle dynamics control, such as braking, chassis, steering, and powertrain systems.

How does vehicle dynamics control 2.0 work, and how do drivers experience the function on the test track?

While other applications merely react, the new vehicle dynamics control acts in advance, based on the signals of vehicle dynamics sensors such as acceleration, yaw rate, steering angle, and wheel speed. Using the principle of feedforward control, the desired behavior of the vehicle is predicted according to the inputs of the driver, and the respective actuators such as braking, chassis, steering, and powertrain systems are actuated in a targeted manner. This increases the driver’s sense of safety and confidence in the vehicle, in everything from everyday handling of the vehicle through to critical driving situations. The driver perceives the behavior of the vehicle as natural and in accordance with their intentions.

This is already experienced in everyday situations such as a simple cruise through the next roundabout. In situations like these, a driving experience matching the car’s DNA can be delivered. When it comes to critical situations such as skidding, the function helps to counteract them even before they are perceived as instability by the driver. Examples of such situations are sudden evasive maneuvers or driving at high speed through tight corners. The system can work so inconspicuously that the driver remains unaware of an active control system and always maintains the optimum level of traction and stability.

Opening up new potential for vehicle manufacturers

Thanks to the strong, ongoing shift toward electrified powertrain systems, centralized and zone-oriented E/E architectures as well as the introduction of by-wire technology, attractive actuator systems are becoming available for vehicle dynamics control. For the first time, existing and future actuator systems are linked together, synergies are created, and additional potential for driving dynamics is opened up.

The outstanding technology used by Bosch even simplifies the implementation of complex demands that vehicles of the future will have to meet – independently of braking, chassis, steering, and powertrain system configurations or vehicle segments. In the near future, flexible deployment of the new vehicle dynamics control system on domain, zone and central control units will be possible.

Using the full potential of by-wire systems

Combining vehicle dynamics control 2.0 with a by-wire system enables stable evasive maneuvers, cornering like on rails and shorter braking distances in slippery road conditions.

With the new vehicle dynamics control 2.0, Bosch utilizes the individual potential of by-wire systems in a seamlessly integrated manner. For instance, Bosch thus enables the integration and optimal utilization of a steer-by-wire system.

With a steer-by-wire system, the mechanical connection between the steering wheel actuator and the rack actuator is eliminated. This enables the standardization of the vehicle cockpit module and chassis across entire vehicle platforms as well as new technical features for more safety, comfort, and agility.

Vehicle dynamics control 2.0 has an active and direct impact on the vehicle’s steering and yaw response. In addition, the elimination of the mechanical connection between the steering wheel actuator and rack actuator prevents unwanted rotational movement on the steering wheel. Therefore, it creates new degrees of freedom in vehicle dynamics control. This delivers obvious benefits to drivers, such as an even more natural vehicle reaction.
