Patent number: 11472389Abstract: A controller for a vehicle is provided. One of a prime mover that drives a front wheel and a prime mover that drives a rear wheel is referred to as a first prime mover, and the other one is referred to as a second prime mover. The controller generates, when a required torque required for a drive wheel of the vehicle is a braking torque, the braking torque from the first prime mover. The controller limits, when the required torque changes from the braking torque to a driving torque, an increase in the driving torque generated from the first prime mover during a set period. The controller generates, from the second prime mover that does not generate the braking torque, the driving torque required during execution of the torque limit process.Type: GrantFiled: November 26, 2019Date of Patent: October 18, 2022Assignee: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Takeshi Kanayama
