    摘要: PROBLEM TO BE SOLVED: To provide a riding-type ground work vehicle which, when traveling on a sloped surface, can travel in a user-intended direction and allows easy and flexible setting the behavioral characteristics of the vehicle that is under control, based on the difference between the detected yaw rate value and the target yaw rate value. SOLUTION: A lawn mowing vehicle 10, which is a riding-type ground work vehicle, includes a controller 48 and a yaw rate sensor 60 which detects the yaw rate of the vehicle. The controller 48 calculates two target rotation speed instruction values for right/left wheel driving electric motors 22 and 24, based on an acceleration instruction and a turn instruction input by a user; obtains two correction factors related, respectively to the right/left wheel driving electric motors 22 and 24, based on the difference between a target yaw rate value and a detected yaw rate value, and corrects for the two target rotation speed instruction values with the two correction factors to control the drive of the wheel driving electric motors 22 and 24.

    摘要: PROBLEM TO BE SOLVED: To provide a hybrid drive device H having superior mountability and capable of employing a relatively compact dynamo-electric machine MG without requiring any high hydraulic pressure. SOLUTION: The hybrid drive device H comprises an input member I connected to an engine E, an output member O connected to a wheel W, a single dynamo-electric machine MG and a pair of planetary gear devices P1, P2 having at least three rotary elements, and is capable of realizing a plurality of gear change stages. One planetary gear device P2 has as a rotary element at least one fixed rotary element to be stopped by a non-rotary member Ds, and functions as a speed-reducing planetary gear device to reduce the rotation of the dynamo-electric machine MG in every gear change stage and to transmit the reduced rotation to the output member O. The other planetary gear device P2 works as a speed change planetary gear device to transmit the rotation of the input member I to the output member through the same speed or the speed change.

    摘要: PROBLEM TO BE SOLVED: To provide a control device for a vehicle, preventing acceleration of the vehicle during slope ascent to avoid impartment of an incongruity sense to a driver, for example, even if constant-speed travel control using driving force and braking force ends without depending on acceleration operation.
    SOLUTION: This electronic control device 50 reduces the vehicle driving force to force (0) according to an acceleration operation amount at a specific control end time point on and after the time point (the specific control end time point) when the constant-speed travel control ends without depending on the acceleration operation and braking operation by operation or the like of a control switch 46A. The electronic control device controls brake oil pressure by use of an oil pressure circuit 33 such that a value of vehicle propulsive force that is force having a positive (negative in the case of the opposite direction) value in the case of the same direction as the driving force, having a value obtained by subtracting magnitude of the braking force from magnitude of the driving force as magnitude becomes not more than a value of the vehicle propulsive force at the specific control end time point to change the vehicle braking force to the force (0) according to the braking operation amount at the specific control end time point.
