Abstract: PROBLEM TO BE SOLVED: To provide a water-cooled engine control device capable of properly executing various controls based on the temperature of cooling water in accordance with changes in a discharge amount of a water pump.SOLUTION: The device includes a water pump that can vary a discharge amount. When the water pump is in an operation stop mode, the control device executes various controls based on an estimated water temperature VT (solid line) estimated by a first estimation mode (t1 to t2). When the water pump is in a suppressed operation mode or a full operation mode, the control device executes various controls based on a cooling water temperature RT (dashed-dotted line) estimated by a second estimation mode (t3 and thereafter). When the estimation mode for a cooling water temperature is switched from a first operation state to a second operation state, the control device calculates a gradually varying temperature Svt (dashed-two dotted line), which gradually decreases with lapse of time setting the estimated water temperature VT estimated by the first estimation mode as an initial value just prior to switching, for a predetermined period (time t2 to t3) immediately after switching, and executes various controls based on the gradually varying temperature Svt.

Abstract: PROBLEM TO BE SOLVED: To provide a vehicle controller that improves followability of travel control. SOLUTION: When a driving support control part 69 performs driving support control to control travel of a vehicle 1, a temporary target trajectory is generated, in a target trajectory arithmetic part 72, from a state of a road acquired in a road state acquisition part 70, and cornering drag that is travel resistance is estimated from the temporary target trajectory in a travel resistance estimation part 71. By use of the cornering drag, a future target trajectory is generated in the target trajectory arithmetic part 72. Accordingly, deviation between the generated target trajectory and a travel trajectory when the vehicle 1 travels can be reduced, and the travel of the vehicle 1 can be controlled be close to the control along the actual travel of the vehicle 1. Thereby, a feedback amount of behavior of the vehicle 1 in the driving support control can be reduced. As a result, the followability in the travel control of the vehicle 1 by the driving support control can be improved. COPYRIGHT: (C)2011,JPO&INPIT
