摘要:
The invention relates to a vehicle provided with a device for preventing shocks from an underbody member, characterized in that said vehicle includes: at least one detector capable of detecting the presence of a foreign object under the body of the vehicle; and an electronic control unit configured to, when a foreign element is detected under the vehicle by the presence detector and the vehicle is put in reverse, apply a braking torque in order to immobilize the vehicle, and then apply a stall torque in order to keep the vehicle immobile.
摘要:
A cooling system for a hybrid powertrain of a motor vehicle comprising a internal combustion engine (2) and an electric traction assembly (3), comprising a main circuit (10) that can be traversed by a coolant in order to cool the internal combustion engine (2) to a first temperature level and a secondary circuit (20) that can be traversed by a coolant to cool the electric traction assembly (3) to a second temperature level, lower than the first level, each of the circuits (10 and 20) comprising a radiator (11 and 21) capable of cooling the coolant by means of heat exchange with an air flow, at least one hydraulic pump (12, 22, 23 and 24) for circulating the coolant in the coolant circuits (10 and 20), and one electronic control unit (30) capable of controlling the hydraulic pumps (12, 22, 23 and 24). The control unit (30) comprises a module for recovering information on the dynamics of the vehicle and a module for controlling the flow from the hydraulic pumps (12, 22, 23 and 24) on the basis of that information.

Method of controlling a switched-mode power supply and corresponding power supply. The invention relates to a method of controlling a switched-mode power supply 1 comprising a switching cell 2 having two series-connected configurable on/off switches (5, 6); in which the switching cell 2 is configured cyclically: for a duration T1, in an on state, in which a first on/off switch 5 is closed and the second on/off switch 6 is open; and, for a duration T2, in an off state, in which the second on/off switch 6 is closed and the first on/off switch 5 is open. In particular, the switching cell 2 is also configured in a transition state, in which the first on/off switch 5 and the second on/off switch 6 are open: for a duration Tm1 between the off state and the on state; and for a duration Tm2 between the on state and the off state; and the durations T1 and/or T2 of the on and off states are determined according to the durations Tm1 and/or Tm2, respectively, of the transition states.
