Abstract:
A vehicle front body structure including a framework member provided at a front end of an upper member which extends forwardly from a front pillar closest to a driver's seat. The framework member includes an inclined portion which extends forward over and beyond a front wheel, and a vertical portion which extends from a front end of the inclined portion in such a manner as to be suspended in front of the front wheel. When, in a collision between vehicles, a front side member of an oncoming vehicle collides with own vehicle at a position outside a front side member in a vehicle widthwise direction, a resulting impact is alleviated by the framework member, precluding the front pillar from being exerted with an excessive amount of impact force.
Abstract:
A vehicle driving force control apparatus which can reduce a driver's embarrassment at difference in accelerator feeling when the driver switches from a constant speed cruise mode to an ordinary variable speed drive mode, and which allows the use of engine brake even while constant speed cruise is requested. The apparatus comprises a switch for constant speed cruise, an accelerator sensor, a brake sensor, a current speed sensor, and a cruise condition judging function for deciding that cruise conditions are satisfied when constant speed cruise is requested, the accelerator pedal is not depressed, and the brake pedal is not depressed, and deciding that the cruise conditions are not satisfied in other cases. It updates target vehicle speed with current vehicle speed when the cruise conditions are not satisfied or on the instant when the cruise conditions are changed from dissatisfied to satisfied and sets controlled output so that current vehicle speed reaches the target vehicle speed. The controller also sets the controlled output when the cruise conditions are satisfied and selects controlled output based only on depression on the accelerator pedal by the driver when the cruise conditions are not satisfied. A throttle valve controls a sucked air amount of an engine based on the selected controlled output.
Abstract:
A throttle control apparatus carries out electronic throttle control, wherein a throttle valve is opened and closed by a motor actuated in accordance with depression of an accelerator pedal. It includes an accelerator lever actuated by the accelerator pedal, a throttle lever provided with the throttle valve, a motor lever actuated by the motor so as to operate the throttle lever in a valve-opening direction and in a valve-closing direction, a limp home lever, and an urging spring for urging the motor lever and the throttle lever in the valve-closing direction. The limp home lever is held rotatably on the throttle lever so as to rotate to an engagement position where it can mechanically engage with the accelerator lever and to a siding position where it cannot mechanically engage therewith. The urging spring also actuates the limp home lever so as to rotate to the siding position when electronic throttle control is carried out by the motor, and actuates it so as to rotate to the engagement position when electronic throttle control is not carried out by the motor.
Abstract:
A throttle control method for an internal combustion engine wherein a motor is connected through a clutch mechanism to a throttle valve which is constantly biased toward a closed position by a return spring. The motor is controlled in accordance with an output signal from a throttle sensor which detects the degree of opening of the throttle valve. This arrangement controls the amount of intake air into the internal combustion engine. The clutch mechanism is engaged and disengaged in accordance with a running condition of the vehicle and an operating condition of the internal combustion engine. An operating condition of the motor, the throttle sensor, the clutch mechanism and the return spring, is detected by activating the motor and the clutch mechanism, and when an abnormality is detected in at least one of the devices, both the motor and the clutch mechanism are deactivated.
