Abstract: When a driver attempts to hurriedly start driving a stopped vehicle, for example, the driver may, without realizing it, begin operating an accelerator pedal before shifting a shift lever from a non-drive position to a drive position. In such a situation, when the shift lever is shifted from a non-drive position to a drive position while the accelerator pedal is being operated, a drive power limiting process is implemented for limiting the drive power when the drive power is output from a drive source in accordance with the amount that the accelerator is being operated. As a result, when the shift lever is shifted from a non-drive position to a drive position in the abovementioned manner, it is possible to restrict starting of the vehicle, which is caused by the transmission of drive power from the drive source to the wheels. This reduces the strange sensation experienced by the driver.

Abstract: A vehicle that improves the accuracy of wheel stopping determination including a stopping determination unit that calculates stopping determination time by multiplying the pulse width of a wheel speed pulse immediately before a non-output time, for which no wheel speed pulse is output from a wheel speed sensor, by 21/2+1, or a corrected time which is corrected on the basis of the stopping determination time is set as a threshold value for determining stopping of wheels. Thus, the time corresponding to the pulse width of the wheel speed pulse takes into consideration the deceleration and traveling distance of the vehicle, thereby obtaining an optimum threshold value for determining the stopping of the wheels.

Abstract: To make a brake device generate a required braking force, a hydraulic control section switches, according to the relative magnitude between the required braking force and a braking force exerted by braking operation, between drive of a pump motor and non-drive of the pump motor and a master cut valve reduces the flow of brake fluid in the direction to a master cylinder. By this, a wheel cylinder maintains hydraulic pressure capable of generating the required braking force. As a result, the pump motor is not necessarily always driven when the required braking force is generated, and the operating time period of the pump motor is reduced. As a result, a load on the pump motor is reduced to enhance durability of the pump motor.

Abstract: An ECU designates a value of a variation “Vunder” based on at least one of information about driver's operation, a velocity, and a road surface gradient when an actual velocity “V” is higher than a target velocity, sets a value of a variation “Vtarget” based on the designated value of the variation “Vunder” and the target velocity, adjusts the velocity of the vehicle to the velocity of the set value of the variation “Vtarget”, and determines whether the actual velocity “V” after the adjustment is a value not greater than the value of the variation “Vtarget”. Then, the ECU converges the velocity of the vehicle to the target velocity after it has been determined that the actual velocity “V” after the adjustment is a value not greater than the value of the variation “Vtarget”.

Abstract: In a vehicle remote operation system that remotely operates a vehicle V using a portable terminal 200, during the remote operation of the vehicle V by the portable terminal 200, when the cab of the vehicle V is not locked, a main control unit 112 of an on-board device 100 does not permit movement of the vehicle V. Therefore, the vehicle V can be remotely operated only when the cab of the vehicle is locked. As a result, it is possible to prevent a malicious person from getting in the vehicle V during the remote operation. In addition, even when a well-meaning person who gets in the cab unexpectedly unlocks and opens the door, the vehicle is stopped. Therefore, it is possible to ensure safety.

Abstract: A vehicle has a shift mechanism and a position detection device that detects an operation position of the shift mechanism. A transmission is brought to a power transmission state when an operation unit of the shift mechanism is operated to a driving position, and is brought to a power interrupt state when the operation unit is operated to a non-driving position. A driving force limitation process for reducing the driving force of an internal combustion engine is executed when it is determined that the non-driving position has been shifted to the driving position on the basis of the operation position of the operation unit as detected by the position detection device. The driving force limitation process is prohibited when it is determined that the vehicle is traveling and that the operation unit is not operated to any of the operation positions.

Abstract: Precise operation of an accelerator operating member (7) is more difficult to perform in a reversing operation of a vehicle (1) as compared with an advancing operation. Therefore, behavior of the vehicle (1) is not smooth and thus tends to be unnatural. In the reversing operation of the vehicle (1), driving force output from an internal combustion engine (2) is limited in accordance with vehicle acceleration (D). At this time, it is possible to regulate the driving force of the vehicle (1) in conformity to the actual operation of the accelerator operating member (7) by the driver. In addition, limitation of the driving force is not executed in the advancing operation of the vehicle (1). At this time, the vehicle (1) can be driven in a state in which the driving force is comparatively small. Therefore, it is possible to prevent the behavior of the vehicle (1) from being unnatural.
