Less rollovers

The cars produced today are getting better and better every year. The progress of the work is aimed at ensuring the safety of movement and meeting the increasingly stringent requirements in the field of environmental protection.

Environmental requirements lead to an annual reduction in fuel consumption by engines and a significant reduction in emissions of harmful components into exhaust gases. In the field of safety, many effective solutions, invisible to the user, have already been implemented, such as anti-lock, traction control and traction control, as well as many devices known to every driver, such as airbags, seat belts and safes. steering columns. However, work on the "car of tomorrow" continues and brings new discoveries.

They predict disaster

An analysis of road traffic accidents in the United States shows that half of all deaths were caused by so-called rollovers. This alarming information inspired designers to develop appropriate sensors to detect the danger of a car tipping over onto its roof. The company that first developed these devices is Bosch.

The concept of early rollover risk detection is based on the analysis of information received from the vehicle speed sensor and 2. acceleration sensors built into the central airbag control unit.

They slow down

The rotation speed sensor provides information about the speed around the vehicle's longitudinal axis, while the acceleration sensors measure the vehicle's lateral and vertical acceleration.

Critical parameters:

- speed of rotation around the longitudinal axis of the vehicle

- accelerations that cause the forces of separation of the car from the road.

After exceeding the limit values ​​of these parameters, a signal is automatically given, which reduces the speed of the car, and at the same time activates the system for improving the safety of passengers, i.e. early activation of the seat belt pretensioners.

The sensors are resistant to temperature fluctuations and mechanical damage and meet all the design requirements of vehicles. The use of these devices in specific solutions is expected this year.
