  • Patent number: 9493144
    Abstract: A vehicle braking apparatus varies a relationship of a pressure increase characteristic of rear-wheel brake oil pressure with respect to a pressure increase characteristic of front-wheel brake oil pressure according to a determination result of a likelihood of a collision with an obstacle. Preferably, when the likelihood of a collision with an obstacle is lower than a predetermined level, the relationship of the pressure increase characteristic of the rear-wheel brake oil pressure with respect to the pressure increase characteristic of the front-wheel brake oil pressure is caused to be a relationship in which a wheel cylinder pressure of the rear wheel increases not earlier than wheel cylinder pressure of the front wheel.

  • Publication number: 20160152273
    Abstract: In a vehicle body front structure, a collision load is input to an outside protruding portion of a gusset when a portion farther to a vehicle width direction outside than a front side member of a vehicle collides in a frontal collision with a colliding object (here, barrier (B)) such as an oncoming vehicle (i.e., when a so-called small overlap collision occurs). This gusset is fixed in a cross section of a front portion of the front side member, so the collision load is able to be better transmitted to a vehicle width direction inside portion of the front side member. Moreover, this gusset abuts against a front end portion of the outer panel of the front side member from a vehicle front side, so the collision load is also able to be better transmitted to a vehicle width direction outside portion of the front side member.

  • Patent number: 9145135
    Abstract: The hybrid vehicle executes a diagnosis of a component related to exhaust qualities during a fuel-cut operation of the internal combustion engine and generates a fuel-cut request to execute the diagnosis. When the internal combustion engine is operated in an idle state, the hybrid vehicle feedback-controls a throttle valve opening (control parameter) such that an engine rotation speed is maintained at a target idle rotation speed, and learns a value corresponding to the control parameter as a learned value for controlling the idle operation in a state where the vehicle speed is not more than a learning permission vehicle speed and the internal combustion engine is operated in the idle state. The hybrid vehicle continues generation of the fuel-cut request until the learning of the idle operation control learned value is completed.

  • Patent number: 8489292
    Abstract: A downshift allowable vehicle speed is variably set according to a torque converter slippage amount. Specifically, a downshift allowable vehicle speed is variably set by, using a reference downshift allowable vehicle speed when the torque converter slippage amount is 0 and a gear ratio of the automatic transmission after a downshift, calculating an allowable vehicle speed correction amount based on the present torque converter slippage amount and the gear ratio after the downshift, and setting a value obtained by subtracting the allowable vehicle speed correction amount from the reference downshift allowable vehicle speed as the downshift allowable vehicle speed. By such setting, it is possible to set a higher downshift allowable vehicle speed as the torque converter slippage amount becomes smaller, so it is possible to expand a downshift allowable region when the manual gearshift mode is selected.

  • Patent number: 8408589
    Abstract: A knee airbag device for a vehicle, configured in such a manner that, when a knee airbag is inflated and expanded with the knees of a vehicle occupant located close to an airbag door, a load to the lower legs is reduced. A first tear section (100) for expanding a first airbag door (108) in the vehicle's top-bottom direction and a second tear section (102) for expanding a second airbag door (112) in the vehicle's lateral direction are formed on the rear surface side of a glove-box-door outer member (24). The first tear section (100) is composed of a left and right pair of vertical tear sections (104) and a first horizontal tear section (106). The second tear section (102) is composed of second lateral tear sections (110).

  • Patent number: 8393345
    Abstract: An oil pressure control device includes a plurality of solenoid valves, and a foreign matter discharge unit which carries out foreign matter discharge treatment for a treatment period composed of a first period T1 in which a current smaller than a predetermined value is supplied to one of the solenoid valves and a second period T2 in which a current equal to or larger than the predetermined value is supplied to the one of the solenoid valves, and makes timings for varying the current values different from one another so as to start supplying a current equal to or larger than the predetermined current value to another one of the solenoid valves at the beginning of the first period T1, and to start supplying a current smaller than the predetermined value to the another one of the solenoid valves at the beginning of the second period T2.

  • Patent number: 7613551
    Abstract: A vehicle remote operation device of optimized fail-safe function is disclosed that directs a vehicle to execute operations in response to a remote operation request made by a user of the vehicle. The vehicle remote operation device has a fail-safe control unit that changes a fail-safe criterion in execution of the remote operation according to a distance between the user and the vehicle. Preferably, the fail-safe criterion is moderated when the distance between the user and the vehicle is short. Alternatively, instead of measuring the distance between the user and the vehicle, a Smart Entry System is used to detect a key carried by the user to determine whether the user is near the vehicle.
