Facts on Vehicle Crash Sensors

Road Accidents are the worst possible incidents one can associate with driving. To reduce the possibilities of car crashes, technology has come forward with several solutions which are now widely accepted by the motor companies. The basis of all automobile safety technologies are the sensors that can smack the probability of a crash and alert the driver. These sensors are now able to control the cars by themselves even without human interference.

Here are a few lines of information shared by the auto body shop on crash sensors that are now held as the basic preventive measures to resist a car crash from all possible corners.

Remote Acceleration Sensors

Today the latest cars are equipped with Crash sensors have now advanced from being simple pressure sensors advanced micro-machined accelerometers. These sensors can sense the actions of acceleration and deceleration in a vehicle that can cause a crash or an accident.

Single-Axis Acceleration Sensors

The traditional single-axis acceleration remote sensors mounted on the chassis-rail- were not quite capable of detecting the pole impacts at the center of the vehicle under any frontal accident condition because of the flexibility in that area of the vehicle. But today the modern systems have improved enough to sense the impact of the vehicle in no time.

Multi-Axis Sensors

The multi-axis sensors that are used in modern systems can measure acceleration in multi dimension at once. These types of sensors have improved the performance in sensing the probability of a crash that is required for rating tests like front pole impact and small overlap impacts.

Moreover, the dual-axis sensors if placed on the B-Pillar are now capable of providing enhanced performance in sensing crashes without any additional pressure or the help of acceleration satellite sensor.

Advanced Sensors

In recent days the latest vehicle acceleration and crash sensor systems available in the market are described below:

Central Acceleration Sensor

The central acceleration sensor can be described as an automotive sensor technology that was introduced by Bosch. It is made on the basis of surface micro-mechanical technology. It is one of the integral part of the safety features working in combination with the airbag control unit. Starting  from the ability to provide signals all along the axes of the vehicle both longitudinal and lateral, these signals can generate the airbag triggering decision in turn and can provide a plausibility signal.

Lateral Acceleration Sensor

The lateral acceleration sensor was introduced by Volkswagen that can measure the lateral acceleration of a vehicle just to determine its real-time position. It is placed on the same section where we find the rotation-rate sensor.

Low-g-Sensor

The low-g-sensor launched by Bosch again is specially designed for sensing the probability of any rollover by the vehicle. This sensor too can measure the acceleration both in the longitudinal and vertical directions. As explained by a popular collision repair shop in Salisbury, making use of the angular rate signal, the algorithm of the sensor can detect the rollover tendency in a vehicle. It can also transmit additional sensor signals in proportion to the vehicle dynamics and enhance the sensing application of a rollover.

The Bottom Line

Thus with the right combination of active and passive safety sensors the crashing incidents can be significantly reduced.
