Les 10 technologies automobiles pour votre sécurité – Hybrid Life

10 Car Security technologies Automatic brake assist Predictive detection with millimetre-wave radar and single or stereoscopic lens camera Visual and acoustic warning signals Automatic full brake application Rear trafic alert Obstacle detection with microwave radars housed within the rear bumper It measures the approach time of vehicles Lane assist Single lens camera coupled with a millimetre-wave radar Assists the driver with steering to keep the vehicle running in the middle of its lane Assists in keeping the vehicle running within its lane even on curves Even when white lines are not visible Lane departure warning Automatic High Beam This system uses a single lens camera in the interior mirror Precollision system (vehicles, cyclists, pedestrians) This system uses a single lens camera located on the inside rear-view mirror and a millimetre-wave radar (or a laser in some vehicles) In case of danger, it activates the emergency brake Detection now distinguishes both bicyclists and pedestrians day and night Blind Spot information System This system uses microwave radars located in the rear bumper Airbags and body rigidity Body rigidity with use of high-strength steels and programmed deformation zone The airbags are triggered between 30 and 150ms
after impact to protect passengers Driver Attention Alert The DAA (Driver Attention Alert) monitors the steering angle given by the driver using direction angle sensors during a driving period to establish a baseline Then it compares the driving modes to the reference level using statistical analysis of steering correction errors correlated with secondary data such as speed, time and air conditioning settings.

Electronic Stability Program When you drive several forces act on your vehicle you probably feel them in your daily behaviour when you take a curve When you turn the wheel, the car does not move only to one side It actually moves around a vertical axis Under certain conditions, the car may turn a little too much or not enough Like when you move away to avoid an obstacle by taking a curve too fast or meet a slippery road that's why the ESP (Electronic Stability Program) was designed It's a set of sensors that monitor continuously how the car behaves according to the driver's instructions The ESP compares the steering wheel information with the speed of each wheel In a few milliseconds, the ESP is able to to know if the car is not following the expected curve.

When you move quickly to avoid an obstacle the car will tend to go straight ahead. The ESP will brake the inner wheel, which will involve a rotational force to answer more precisely to the driver's orders. The ESP will brake the front wheel to help rotation. To get the car back on track. If necessary, the ESP will reduce the engine power. This is to restore control more quickly..
