CONTROL SYSTEM FOR VEHICLE
A control system is for a vehicle (Ve), and the control system comprises an electronic control unit (18). The electronic control unit (18) is configured to (i) produce differential rotation by controlling a rotational speed of either a first clutch member (24) or a second clutch member (25) of a selectable one-way clutch (17) by a motor (2), and (ii) execute the following processes in an order of (1.) to (4.) in the case where the electronic control unit (18) switches the selectable one-way clutch (17) from a disengaged state to a engaged state: (1.) controlling the motor (2) such that the differential rotation becomes the negative differential rotation; (2.) switching the selectable one-way clutch (17) from a second state to a first state; (3.) controlling the motor (2) such that the differential rotation becomes the positive differential rotation; and (4.) engaging a part of a strut with a part of the second clutch member (25).
CLUTCH CONTROL SYSTEM AND METHOD FOR MITIGATING DRIVELINE SHOCK LOADS AND PREVENTING MECHANICAL FAILURE
A clutch control system mitigates driveline shock loads in a vehicle. The clutch control system has 1) A friction clutch capable of transitioning between a fully open, a partially open, and a fully closed position; 2) A control unit configured to receive vehicle data, wherein the vehicle data comprises current engine torque, and define one or more operational modes of the friction clutch, wherein the one or more operational modes comprise a driveline protection mode defined by having an operating range between the fully open position and an effectively closed position of the clutch, wherein the effectively closed position is a partially open position having a torque capacity that exceeds the current engine torque, thereby preventing clutch slip at the effectively closed position; and 3) A clutch actuator configured to operate the clutch in accordance with the one or more operational modes, including the driveline protection mode.
