Vehicle Mass Computation |
摘要 |
A vehicle having a drivetrain is controlled based on a difference between a torque transmitted by the drivetrain when the vehicle has constant non-zero speed and the torque transmitted by the drivetrain when the vehicle is accelerating. The drivetrain torque may be measured by a drivetrain torque sensor. The effective vehicle mass is computed from the torque difference. The computed mass of the vehicle is used to adjust the activation of a collision warning system or a collision avoidance system. A method of operating a vehicle where the activation of a collision avoidance system is adjusted based on a difference between a torque transmitted by a drivetrain when the vehicle has constant non-zero speed and the torque transmitted by the drivetrain when the vehicle is accelerating is disclosed. The torque difference is used to compute a vehicle mass that is used to adjust a collision warning distance. |

1. A vehicle comprising:
a drivetrain; and at least one controller programmed to control operation of the vehicle based on a torque transmitted by the drivetrain measured when the vehicle has constant non-zero speed and the torque transmitted by the drivetrain measured when the vehicle is accelerating. |
