Job title



Conventional vehicle dynamics control systems have two major functions when it comes to vehicle motion control. First, they make vehicles stable and safer in critical driving situations through wheel individual braking interventions. Second, they excite the driver by brand-specific vehicle dynamics response and agility. The ongoing and strong transition to electrified powertrain systems and the introduction of by-wire technology are making attractive actuator systems available for vehicle dynamics control, in addition to the traditionally used braking systems. They give rise to new potentials for the control of vehicle dynamics and at the same time impose new requirements to the control system. Thus, modern vehicle dynamics control systems need to be capable of managing cross-domain actuator control, keeping system complexity low, creating synergies, and unlocking the full potential of each single actuator in any driving situation. Further, the ongoing trend to more centralized and zone-oriented vehicle E/E architectures is another major technological challenge in developing a future-proof vehicle dynamics control system. As the global market leader for vehicle dynamics control systems, Bosch has taken up these trends several years ago and is now introducing the next generation vehicle dynamics control system, Bosch Vehicle Dynamics Control 2.0. It will be launched in the European vehicle mass and premium sports car market from 2023 onwards. Vehicle Dynamics Control 2.0 incorporates a completely re-designed smart controller concept. It is based on a model-based feed-forward control approach which allows to anticipate the vehicle behaviour instead of just reacting to a sudden event. As a result, vehicle passengers benefit from a much more agile, safe, and natural driving experience. Finally, the integrated controller concept allows to easily integrate, control, and utilize various actuators for vehicle dynamics control. Car makers are relieved of complex tasks such as coordinating single and independent control systems while at the same time benefiting from synergies. From the first line of code, Bosch experts have strictly followed three design principles of software-defined vehicles. First, Bosch has abstracted its vehicle dynamics control system from a specific hardware component. As a result, Vehicle Dynamics Control 2.0 will enable flexible deployment on components based on standardized interfaces. Second, the modular architecture of Vehicle Dynamics Control 2.0 enables to scale and apply the controller to any vehicle segment as well as any powertrain configuration. It even allows integration of further relevant actuators, like steering systems. Finally, Vehicle Dynamics Control 2.0 has low dependency on other controller functions. This enables a long-term evolution of the controller, flexibility in customization and deployment as well as updates without excessive complexity and cost. Vehicle Dynamics Control 2.0 from Bosch demonstrates a revolutionary step in vehicle dynamics control systems. It is no longer a domain-specific function but rather rapidly evolving into a cross-domain coordination and control system, anticipating modern and future vehicle development technology trends.
