Abstract
Methods and systems are provided for reducing vehicle movement during standstill. In one example, a method for a hybrid or electric vehicle may include monitoring a requested torque of an electric machine and a clutch position, predicting a torque at an output shaft by multiplying the requested torque and clutch position, and operating the hybrid or electric vehicle in a default state in response to an indication of a predicted torque exceeding a threshold torque.
Claims20
A method for a hybrid or electric vehicle comprising:
- monitoring a requested torque of an electric machine and a clutch position;
- predicting a torque at an output shaft by multiplying the requested torque and clutch position;
- and
- operating the hybrid or electric vehicle in a default state in response to an indication of a predicted torque exceeding a threshold torque.
A method for a vehicle having an electric machine comprising:
- monitoring a torque requested by an inverter of the electric machine and a clutch position;
- predicting the torque at an output shaft by multiplying a requested torque and clutch position;
- monitoring a speed of the vehicle;
- deriving an acceleration of the vehicle in response to an indication of the speed exceeding a threshold speed;
- and
- operating the vehicle in a default state in response to the indication of at least one of the predicted torque exceeding a threshold torque and the acceleration exceeding a threshold acceleration.
A standstill control system for a vehicle, comprising:
- an electric driveline having an inverter of an electric machine and a clutch;
- a controller communicatively coupled to the electric driveline;
- a vehicle speed sensor coupled to the controller;
- and
- a memory storing executable instructions that, when executed, cause the controller to monitor a torque requested by the inverter of the electric machine and a position of the clutch;
- predict the torque at an output shaft by multiplying a requested torque and the position of the clutch;
- monitor a speed of the vehicle;
- derive an acceleration of the vehicle in response to an indication of the speed exceeding a threshold speed;
- and
- operate the vehicle in a default state in response to an indication of at least one of the predicted torque exceeding a threshold torque and the acceleration exceeding a threshold acceleration.
