  • Patent number: 11110925
    Abstract: A vehicle controlling device includes: a VSA-ECU that performs deceleration control of a host vehicle using an inter-vehicle distance between the host vehicle and another vehicle traveling in front of the host vehicle; and an engine control unit that performs idling stop control of stopping drive of an engine as a driving source of the host vehicle upon satisfying stop conditions including a condition that vehicle speed of the host vehicle enters a predetermined low vehicle speed range and performs restart control of restarting the engine upon satisfying a predetermined restart condition. A power supply mounted on the host vehicle is used in common as a power supply used in executing the deceleration control and a power supply used in executing the restart control. The engine control unit prohibits execution of the idling stop control during execution of the deceleration control.

  • Publication number: 20100262349
    Abstract: In a method for assisting a driver during a hill start, the vehicle is held automatically at a standstill using a brake, and when a starting command is detected, the brake is released automatically if the engine torque or an equivalent variable exceeds a specified release threshold value. The vehicle is able to be prevented from rolling back, when the brake is released, by monitoring the engine torque or the equivalent variable for a change which is not due to the actuation of the accelerator, and by modifying the condition for releasing the brake when a change in the engine torque or in the equivalent variable has been detected.

  • Patent number: 7364024
    Abstract: An apparatus for driving and braking a cutting blade of a lawn mower is disclosed. The apparatus includes a shaft for rotating the blade, and a pulley driven by the engine. The shaft extends through a housing. The apparatus includes means for biasing the pulley toward the housing, and means for translating the pulley away from the housing. The apparatus has a stopped position in which the pulley and housing are in friction contact, and has a cutting position in which the pulley and housing are not in friction contact. When power is delivered from the engine to drive the pulley, the apparatus moves from the stopped position to the cutting position such that the pulley and the housing are not in friction contact and the blade rotates. When power ceases being delivered to the pulley, the apparatus moves from the cutting position to the stopped position such that the pulley and the housing are placed in friction contact and the blade stops.

    Abstract: In a vehicle having idle stop functions and low vehicle speed-following drive functions, when a vehicle automatic stop flag F2 is identified as 1 at step S220, determines whether all engine stop conditions except depression of brake pedal are satisfied in step S240. When it is determined all the engine stop conditions except depression of the brake pedal are satisfied, ignition and fuel injection in each cylinder of engine are stopped to automatically stop the engine in step S260. In this arrangement, the driver's depression of brake is excluded from the engine stop conditions. Therefore, even when the motor vehicle automatically stops without the driver's depression of brake, the engine is automatically stopped.

Thus, the delay to recover the motor capacity at the time of returning from the automatic shutoff that is activated during winding-up of a load does not occur, and a control response is increased.
