AI Technical Summary
Technical Problem
Hybrid vehicles cannot shift gears when the engine is off, which prevents the four-wheel drive system from switching and affects the user's driving experience.
Method used
By monitoring the vehicle's engine shutdown status, it determines whether the vehicle is in pure electric drive mode. In pure electric drive mode, it sends a corresponding signal to the four-wheel drive system to respond to the shift command and perform a shift operation. In non-pure electric drive mode, it sends a non-pure electric drive mode signal to avoid responding to the shift command.
Benefits of technology
It enables gear shifting even when the vehicle is off, enhancing the user's driving experience.
