Solutions for more safety on the road

Lorem ipsum dolor

An accident-free future – this is Bosch’s vision for the mobility solutions of tomorrow. Every new Bosch innovation today brings this ambitious target one step closer. These Bosch developments therefore ensure that accidents, injuries and damage to the vehicle can be more easily avoided: Safety made by Bosch

1) ABS And ESP

Lorem ipsum dolor

Electronic driving safety systems are designed to prevent accidents or minimize damage. With ABS, TCS and ESP®, Bosch is one of the pioneers in the field of active driving safety.

Originally conceived as special equipment for luxury cars, electronic driving safety systems have since became standard for many new vehicles – even in the compact class. Safety made by Bosch.

ABS Anti-Lock Braking System: Braking and Steering

In critical driving situations, e.g. wet or slippery roads, startled or shocked driver , the wheels can get locked when braking. This makes it impossible to steer the vehicle. The anti-lock braking system (ABS) detects incipient locking of one or more wheels at an early stage and selectively reduces the braking pressure. This ensures that the driver can avoid obstructions even with full braking and can brake the vehicle and bring it to a stop safely and quickly.

ABS-and-ESP

EPS – Electronic stability control

ESP enables drivers to brake more safely as the system prevents the wheels from locking. The car still responds to the driver’s steering input even under heavy braking or with a slippery road surface. The vehicle remains stable and the driver can avoid obstructions.

ESP®: A System Which Can Save Lives

Longitudinal and lateral forces act on every car when driving. The driver can stably drive the car for as long as the shear force reserves on the tires are sufficient. If these do not reach a certain level, however, then stable handling is no longer guaranteed. ESP® prevents skidding right from the onset and therefore counteracts one of the main causes for serious and fatal accidents.

The ESP® Components Are:

  • Hydraulic modulator with add-on control unit
  • Wheel speed sensor
  • Steering angle sensor
  • Yaw rate and lateral acceleration sensor

Perfectly usable as an Exchange Unit: Electrohydraulic Brakes

Several years ago, the first Mercedes-Benz model with electrohydraulic brakes (EHB) from Bosch was launched onto the market. Now, Bosch has included the EHB unit as an exchange part in its exchange range. This means that now, even independent workshops can repair defective electrohydraulic brake systems. The ESI[tronic] workshop software offers the perfect support for this process. Mercedes-Benz AG has used the Bosch electrohydraulic brake under its SBC brand in the E-Class (W211), SL (W230), SLR (W199) and CLS (W219) models.

A Safety Buffer for When it Counts

Bosch provides airbag control units which are scaled to all vehicle classes through to the premium segment. The hardware and additional functions of these electronic occupant protection systems can be tailored to the most diverse customer needs.

The “low price” vehicle class is becoming increasingly important for car manufacturers and buyers. Particularly strong growth in demand for cars of this class has been observed in emerging markets. These call for cost-optimized occupant protection electronics. With the airbag control unit AB light, Bosch offers a solution for basic occupant protection requirements and thereby extends its product family of airbag control units.

Airbag

Characteristics and Operating Principle:

The centrally-sensing airbag control unit AB light is based on a standardized control unit concept. It builds upon tried-and-tested Bosch electronics components. AB light uses Bosch’s own system ASICs. This consequent use of standardized components makes it possible to reduce project-specific development and tool costs. The number of components is significantly reduced.

The airbag control unit AB light can be adjusted to many requirements, despite its standardized product approach. A system ASIC with four ignition circuits is available. An expansion to eight ignition circuits and two interfaces to peripheral sensors is possible thanks to the modular system which is used.

Advantages:

  • Specially adjusted to the basic requirements of the low-price-vehicle segment
  • Small size and reduced weight thanks to innovative housing and connector concept
  • Adaptable product concept based on standard components
