Abstract
A vehicle includes a powertrain configured to transfer energy to a tire and including both an engine and an electric machine. The vehicle also includes a controller configured to charge a traction battery with torque captured by the electric machine in excess of torque required to maintain the departure. The charging is in response to indication of departure from static friction between the tire and a surface during a line lock tire slip event powered by the engine.
Claims17
A vehicle comprising:
- a powertrain configured to transfer energy to a tire and including both an engine and an electric machine;
- and
- a controller configured to, in response to indication of departure from static friction between the tire and a surface during a line lock tire slip event powered by the engine, charge a traction battery with torque captured by the electric machine in excess of torque required to maintain the departure and maintain an angular velocity of the tire above a threshold during the line lock tire slip event.
A vehicle comprising:
- a powertrain configured to transfer energy to a tire and including an internal combustion engine;
- and
- a controller configured to, in response to indication of departure from static friction between the tire and a surface during a line lock tire slip event powered by the engine, store energy, that is based on an angular velocity of the tire, in excess of torque required to maintain the departure in an energy storage device and maintain the angular velocity above a threshold during the line lock tire slip event.
A vehicle comprising:
- a front wheel assembly including a brake;
- a rear traction wheel assembly having a tire and being coupled to a powertrain having an engine and an electric machine;
- and
- a controller configured to, in response to acceleration of the engine causing slippage of the tire during a line lock event of the brake, engage the electric machine with the powertrain to charge a traction battery such that a speed of the tire is reduced and the slippage is maintained.
