Vehicle controller for tire blowout control, control method for tire blowout control, and electric vehicle

A control method for tire blowout control of an electric vehicle, wherein the control method is used to control a rear-wheel steering system of the electric vehicle after a tire of a front wheel of the electric vehicle blows out in a traveling process in which a vehicle speed of the electric vehicle is greater than a preset vehicle speed, and the control method comprises:

• at a first moment, detecting that a tire of a front wheel of the electric vehicle blows out, wherein a tire pressure of the front wheel is less than a pressure threshold and/or, in preset duration, a wheel speed increment of the front wheel is greater than a wheel speed increment of another wheel;
• in a first time period after the first moment, controlling the rear-wheel steering system to adjust steering angles of the rear wheels;
• and
• in the first time period or at a second moment after the first time period, in response to a traveling trajectory offset of the electric vehicle being less than an offset threshold or the vehicle speed of the electric vehicle being less than a safety threshold, controlling the steering system to reduce the steering angles of the rear wheels to zero.

An electric vehicle comprising:

• a rear-wheel steering system that is configured to control steering angles of rear wheels of the electric vehicle;
• a vehicle controller;
• and
• a vehicle sensor;
• wherein the vehicle sensor is configured to output a vehicle signal, and the vehicle signal indicates a vehicle speed, a yaw velocity of the electric vehicle, and a tire pressure of each wheel of the electric vehicle;
• and
• the vehicle controller is configured to:
• after a tire of a front wheel of the electric vehicle blows out in a traveling process in which a vehicle speed of the electric vehicle is greater than a preset vehicle speed, control the rear-wheel steering system to adjust the steering angles of the rear wheels.
