MONITORING OF RECOVERY OF RECOVERY BRAKE TORQUE BY AN ELECTRIC DRIVE MACHINE OF A LAND VEHICLE

Abstract

A monitoring method is implemented in a land vehicle comprising a powertrain including at least one electric drive unit associated with a main battery and capable of recovering regenerative braking torque and converting it into a charging current for the main battery. This method includes a step (10-30) in which, when regenerative braking torque is recovered and exceeds a first chosen threshold, further recovery of regenerative braking torque is prohibited.

Claims

8. Computer program product comprising a set of instructions which, when executed by processing means, is capable of implementing the monitoring method according to one of claims 1 to 7, in a land vehicle (V) comprising a powertrain comprising at least one electric motor (MMj) associated with a main battery (BP) and capable of recovering a regenerative braking torque and transforming the latter into recharging current for said main battery (BP), to monitor the recovery of regenerative braking torque.

9. Monitoring device (DS) for a land vehicle (V) comprising a powertrain comprising at least one electric motor (MMj) associated with a main battery (BP) and capable of recovering a regenerative braking torque and transforming the latter into recharging current for said main battery (BP), characterized in that it comprises at least one processor (PR1) and at least one memory (MD) arranged to carry out the operations consisting, when a regenerative braking torque is recovered and the latter is greater than a first chosen threshold, in triggering a prohibition of this recovery of regenerative braking torque by said electric motor (MMj).

10. Land vehicle (V) comprising a powertrain comprising at least one electric motor (MME) associated with a main battery (BP) and capable of recovering a regenerative braking torque and transforming the latter into recharging current for said main battery (BP), characterized in that it further comprises a monitoring device (DS) according to claim 9.
