Vehicle controller and vehicle control method

A method of controlling a vehicle,

• the vehicle including:
• a driving wheel;
• an accelerator opening degree sensor that detects an acceleration request amount of a rider;
• a prime mover that generates torque to be transmitted to the driving wheel in accordance with the acceleration request amount detected by the accelerator opening degree sensor;
• and
• a boost switch to which the rider inputs a boost command,
• the method comprising:
• when a boost request is not being generated, determining, as target torque of the prime mover in accordance with a normal rule, normal torque which corresponds to the acceleration request amount;
• when the boost request is generated under a first condition, determining, as the target torque in accordance with a first boost rule, first boost torque larger than the normal torque;
• and
• when the boost request is generated under a second condition different from the first condition, determining, as the target torque in accordance with a second boost rule different from the first boost rule, second boost torque that is larger than the normal torque and different from the first boost torque, wherein:
• the boost request is generated by an operation of the boost switch by the rider;
• the first condition includes a condition that it has been determined that the vehicle is in a stop state;
• the second condition includes a condition that it has been determined that vehicle-start acceleration of the vehicle has been terminated;
• and
• the first boost rule and the second boost rule are set such that a difference between the normal torque and the second boost torque at a time of the generation of the boost request under the second condition is larger than a difference between the normal torque and the first boost torque at a time of the generation of the boost request under the first condition.

A vehicle controller that controls a vehicle,

• the vehicle including:
• a driving wheel;
• an accelerator opening degree sensor that detects an acceleration request amount of a rider;
• and
• a prime mover that generates torque to be transmitted to the driving wheel in accordance with the acceleration request amount detected by the accelerator opening degree sensor,
• the vehicle controller comprising processing circuitry configured to control the prime mover, wherein:
• when a boost request is not being generated, the processing circuitry determines, as target torque of the prime mover in accordance with a normal rule, normal torque which corresponds to the acceleration request amount;
• when the boost request is generated under a vehicle-start condition, the processing circuitry determines, as the target torque of the prime mover in accordance with a vehicle-start boost rule, vehicle-start boost torque obtained by adding first additional torque to the normal torque;
• when the boost request is generated under a vehicle-travelling condition, the processing circuitry determines, as the target torque in accordance with a vehicle-travelling boost rule different from the vehicle-start boost rule, vehicle-travelling boost torque obtained by adding second additional torque to the normal torque, the vehicle-travelling condition being a condition that an acceleration state by a vehicle start is terminated or a condition different from the acceleration state;
• and
• the vehicle-start boost rule and the vehicle-travelling boost rule are set such that the second additional torque is larger than the first additional torque when the first additional torque and the second additional torque correspond to the same acceleration request amount.
