Advanced ESP functionality

Bosch (Germany) is starting series production of the ESP plus (Electronic Stability Program). With this version of Generation 9, several safety and assistance functions in addition to the anti-skid system may be integrated into the car. It enables OEMs to integrate features such as adaptive cruise control with a stop-and-go function. In launching this version, the company is supporting the increasing spread of these assistance functions in compact and middle class vehicles.

THANKS TO THE MODULAR DESIGN OF HARDWARE and software, different variants of the system may be installed. This enables OEMs to select the required system. The basic version already offers protection against skidding. Moreover, sensors to measure yaw rate and lateral acceleration can be integrated into the electronics of the control unit. With the control of the return pump, pressure control valves, and two additional pressure sensors, the program may precisely regulate brake pressure even when the brakes are applied very lightly. This is important for comfort functions such as adaptive cruise control (ACC).
The ESP premium completes the portfolio, enabling advanced comfort functions. This version of the system has a return pump with six pistons, which generate pressure quickly and constantly. They do this with very little noise and virtually without vibration.
With this ESP version, the carmaker and Bosch have developed an adaptive cruise control system that includes a stop-and-go function. In addition, this vehicle also features company’s LRR3 radar sensor. The stop-and-go function brakes automatically in stop-and-go traffic until the car stops. If the car only stops for a short moment, it starts off again automatically. If the car is stopped for a longer time, the driver needs only to step lightly on the gas pedal to reactivate the function.

The automotive supplier has received the Global NCAP (New Car Assessment Programme) Award 2012 for developing and launching the ESP. The award was presented on May 24, 2012, during the consumer safety organization’s annual meeting in Malacca, Malaysia. Over the years, the company has received many awards for developing and launching ESP. For instance, it was awarded the Allianz Genius safety prize in 2005, and in 2007 the Fédération Internationale de l'Automobile awarded Bosch its FIA World Prize for Road Safety, the Environment, and Mobility.

Automotive Technology is the largest business sector of the Bosch Group. According to preliminary figures, its sales to 59 % of total group sales, in fiscal 2011. Worldwide, more than 175000 Automotive Technology associates work in seven areas of business: injection technology for internal-combustion engines, powertrain peripherals, alternative drive concepts, active and passive safety systems, assistance and comfort functions, in-car information and communication, as well as services and technology for the automotive aftermarket. Bosch has been responsible for such automotive innovations as electronic engine management, the ESP anti-skid system, and common-rail diesel technology.
