CAPCHOC: Vehicle system to detect pedestrians on a short range

This system based on a capacitive sensor integrated in the front face of a vehicle allows to detect a pedestrian (by modification of the electric field generated by the sensor on a short range) and offer the capability to trigger a protection device before the impact (e,g airbag…).

The capacitive sensor is coupled with a signal treatment software which allows to accurately discriminate the presence and the distance of a pedestrian.     

Benefits:

• Short range detection of a pedestrian before impact and low sensitivity to the environment constraint (rain, saline smog…)
• High selectivity of the pedestrian detection via a powerful discrimination of the type of obstacle
• Optimized analysis of the approach parameter (vehicle speed, distance)
• Easiness to integrate the sensor system (metallic screen)
