lucid To be remember its a few hundred new ones Air sedans to solve a mechanical problem that can lead to loss of transmission power. The EV startup says the problem may be present in only a handful of their vehicles (with 99.999% confidence, nothing more) because believe it or not, there’s an application to the problem. there. We’re a bit flawed, but like Tesla and a slew of mainstream automakers have followed, Lucid is empowering its over-the-air update (OTA) system to help solve the problem.
As we noted at the top, the problem here is really a moving part: the spring. It is integrated in a component called a contactor, which is an electrically activated switch that controls the flow of electricity to the electric drive system. When the contactor is open, clean air equivalent to “Accessories” mode in ICE; radio and so on can be used, but the car’s Electric motor is not available. The spring we mentioned above keeps the contactor open (off). When the vehicle is started, the computer (powered by the accessory) activates an electromagnet that pulls the switch closed (on). In some cases, Lucid says the spring force can overcome the force of the magnet, causing the contactor to stick in the open (off) position without warning.
“If a contactor suddenly opens while driving, the vehicle’s electric motor will no longer be energized. This can lead to loss of thrust without prior warning and may increase the risk of injury. collision,” the Lucid bug report said. “The driver will not receive a warning before the contactor opens unexpectedly due to this condition. When the contactor opens unexpectedly, the driver will receive a notification of a system failure and reduced steering power. Vehicle monitor, power steering system and power brake will continue to function because they are not powered by the high voltage system.”
This is where Lucid’s OTA trick comes into play. The company’s software team included a diagnostic tool in a recent update. This tagging feature can detect the electronic signature created when the spring overwhelms its magnet inside the contactor. With this data, Lucid knows which cars need a technician’s attention. The only exceptions are those that for whatever reason have not been updated to the latest version of Lucid’s built-in software; they will be asked to update their vehicle as the first step in the recall process.
Several owners have been informed of the issue; Those whose vehicles are identified later in the process will be notified starting April.
