  • Publication number: 20150073621
    Abstract: A driving support device includes a sensor for acquiring object information on an object outside a vehicle; and a processing device for suppressing driving support, which is based on the object information, if an operation frequency of a wiper is equal to or higher than a predetermined reference and for providing the driving support if the operation frequency of the wiper is lower than the predetermined reference and if a vehicle speed is higher than a predetermined vehicle speed.

  • Patent number: 8961370
    Abstract: A vehicle control apparatus includes a controller that performs control such that an engine output does not increase when a control mechanism and a brake override are operated simultaneously, wherein the control mechanism controls the engine output independently of an accelerator operation amount, and wherein the brake override system reduces the engine output in response to simultaneous operations of an accelerator and a brake.

  • Patent number: 8745980
    Abstract: A vehicle control device, that controls to suppress a driving force of a vehicle based on an operation of a brake pedal operated when a braking force is generated by a braking device, wherein the brake pedal is connected to a brake booster, that increases an operating force input to the brake pedal by using a brake negative pressure to transmit to brake fluid of the braking device in order to appropriately control by appropriately detecting the operation of the brake pedal; and the driving force is suppressed according to an M/C pressure when the brake negative pressure is higher than a brake negative pressure threshold value, and the driving force is suppressed according to an operation state of the brake pedal when the brake negative pressure is equal to or lower than the brake negative pressure threshold value.

  • Publication number: 20140136084
    Abstract: A brake override system (BOS) (1) prioritizes braking when both an accelerator and a brake are operated simultaneously by reducing the required accelerator operation amount value that is used to control drive force so that it is lower than the actual accelerator operation amount. The BOS (1) thus achieves a balance between hill-start performance after operation by the BOS (1) is cancelled and stopping performance during operation of the BOS (1) by increasing the required accelerator operation amount value at the time at which the return of the required accelerator operation amount value to the actual accelerator operation amount is initiated when the simultaneous operation of the accelerator and the brake ends.

  • Publication number: 20140129049
    Abstract: A brake override system detects a brake operation based on master cylinder pressure when the brake operation followed by an accelerator operation results in simultaneous performance of the accelerator operation and the brake operation. The brake override system detects the brake operation by a brake switch when the accelerator operation followed by the brake operation results in the simultaneous performance of the accelerator operation and the brake operation. Thus, the system may accurately detect the brake operation regardless of the order of the accelerator operation and the brake operation.

  • Publication number: 20140095045
    Abstract: An electronic control unit performs a reduction control for reducing vehicle drive force when the accelerator and the brake are operated simultaneously. The electronic control unit also varies the amount of decrease in the vehicle drive force during the reduction control and conditions under which the reduction control is implemented depending on the order of the accelerator operation and brake operation resulting in the above-noted simultaneous operation. For example, the amount of decrease in the vehicle drive force is less when the brake is operated first in comparison with when the accelerator is operated first. Thus, it is possible to operate the vehicle drive force in accordance with the intention of the driver.

  • Publication number: 20140038774
    Abstract: When simultaneous depression of an accelerator pedal (2) and a brake pedal (4) is detected, an electronic control unit (1) inhibits a downshift of an automatic transmission (11) and performs output suppression control for an engine (6), thereby making it possible to suppress the increase of vehicle drive force caused by the downshift and maintain a constant vehicle deceleration rate by an easier operation.

  • Publication number: 20140039774
    Abstract: An electronic control unit (1) stops output suppression control for an engine (6) at the time of simultaneous depression of an accelerator pedal (2) and a brake pedal (4) when the depression of the brake pedal (4) is erroneously detected due to an ON-failure of a stop lamp switch (5) even if the brake pedal is not depressed.
