An expert points “the calibration of the sensors in the windshields”

The car manufacturers will be questioned after cases of unexpected vehicle braking, for no apparent reason, which have caused accidents in recent months. Consequently,

The government seeks to better understand the origin of “ghost brakes”. Similarly, The Ministry of Transport announced Friday. Therefore, August 15, launching an investigation on Friday, August 15, after several reports of vehicles which brake on its expert points “the calibration sensors own, unexpectedly and without apparent reason.

Joanna Peyrache is one of the whistleblowers. The young woman was the victim of brutal braking of her car on the highway last April. “She stopped. without action on my part and when there was no obstacle before me, tells Joanna Peyrache to France Inter. It went very quickly, three seconds to arrive at the stop. The car behind came to hit me, and my vehicle made 180 degrees.”

There was no injuries but after the accident. the expertise of his vehicle is refused by the justice, then the driver launched a testimonial call. Since then, she has received 250 reports. “This concerns different brands of vehiclesshe explains. This goes from the small accident to the biggest accident, with deceased people. “

Joanna Peyrache had an exchange with the monitoring of the vehicle and engines market. This service, which depends on the Ministry of expert points “the calibration sensors Transport, will launch evaluations and question car manufacturers. But for motorists victims of these “ghost braking”, the culprit is already found. In a petition launched on the assembly site on August 6. they explain that “The common point between all these incidents is the presence of a driving aid system, especially braking” on new or recent vehicles.

For Christophe Theuil, vice-president of the French Federation of Automobile Expertise, there is “Do not worry a priori”. Questioned by franceinfo. he advances “Technological limits”especially due to “Environmental conditions unfavorable to the detection of sensors, such as rain, fog, snow, darkness or the shaving sun”. According to him. the real subject is “The calibration of sensors and radars that are in the windshield of vehicles”which is not always made when it is replaced.

“It is as if you roll with correction glasses, but which are not well settled to expert points “the calibration sensors your sight.”

This technology. already present for more than fifteen years, “is compulsory on all new vehicles made in Europe since 2022”recalls Christophe Theuil. “There is a risk profit which is really favorable to all electronics. because it has avoided many damage“, advances the vice-president of the French Federation of Automobile Expertise.

The fact that the Ministry of Transport is concerned about the problem of untimely braking is “A fairly. reasonable posture”adds Christophe Theuil. “The investigation will determine if we are on a human failure of driving. on a failure after a maintenance such as the calibration which would not have been made, or if we are really on a sensor problem”he assures.
