Abstract:
A hybrid vehicle having an engine and a motor to be controlled independently of each other for running the vehicle. This hybrid vehicle is given a braking demand detecting function to detect a braking demand through an idle ON of the engine while the vehicle is running, and a first braking function to suppress the rise in the vehicle speed of the vehicle by a regenerative braking force of the motor if the braking demand is detected by the braking demand detecting function.
Abstract:
An electric motor vehicle includes: a floor frame with the front and rear portions raised; four wheels arranged, two at the front and two at the rear of the floor frame; a steering handle projected upward in the front portion for steering the front two wheels; an electric motor for driving the two rear wheels; an inverted U-shaped seat frame projected upward in the rear portion; and a seat with a backrest, adjustable in height and mounted on the seat frame. A rear-side housing is attached on the rear side of the seat frame. In this housing the electric motor, a controller and a charger are arranged in this order from the bottom while a cooling fan with a louver is arranged in the upper portion of the housing.
Abstract:
An electric vehicle braking control device includes a battery, an electric motor driving at least one wheel with electric energy of the battery, an electric energy re-generating mechanism that restores electric energy generated to the battery, a static pressure generator generating fluid pressure according to a brake pedal depressing force, a dynamic pressure generator generating a fluid pressure substantially equal to that generated by the static pressure generating mechanism, a first braking mechanism connected to the static pressure generating mechanism, a second braking mechanism connected to the dynamic pressure generating mechanism, a valve disposed in a fluid conduit connecting the dynamic pressure generating mechanism to the second braking mechanism to generate designated differential pressure with no steps, and a control that controls the valve to generate a differential pressure corresponding to the fluid pressure equivalent to the re-generating braking force applied by the electric energy re-generating mechanism.
Abstract:
An operating apparatus for an automatic transmission, comprises: a select lever connected to the automatic transmission end; a first rotation supporting point provided at a middle position of the select lever and supporting the select lever in such a manner as to freely rotate; a second rotation supporting point provided at a position apart from the first rotation supporting point in the select lever at a predetermined distance; an operating lever rotatably connected to the select lever through the second rotation supporting point; a positioned member provided at a predetermined position in the operating lever; and a positioning member for determining a position of the positioned member to a predetermined position.
Abstract:
A traction control apparatus for a four-wheel drive vehicle simultaneously sets an equal control amount nullVWRLnullnullVWRR for brake devices on the side of rear-left and rear-right wheels if at least one of the rear wheels is driven with a low grip degree. Thereby the slip tendency of the rear wheels is weakened, and the behavior of the vehicle is shifted in a stabilizing direction.
Abstract:
This invention relates to an engine stall prevention apparatus for a hybrid vehicle. This engine stall prevention apparatus comprises a clutch operation detection device which detects an operation of a clutch; a clutch state determination device which determines the state of the clutch based on the relationship between the vehicle speed and the engine speed; a throttle opening degree determination device which determines the degree of throttle opening of the engine; a first engine speed modification device (S010) which modifies a charging/regeneration allowing lower limit engine speed value above which deceleration regeneration by the electric motor is allowed; and a half-engaged clutch determination maintaining device (S008) which outputs a determination signal indicating that the clutch is half-engaged for a predetermined period of time when the throttle is completely closed and the clutch is determined to be half-engaged. When a half-engaged clutch determination is maintained, the first engine speed modification device elevates the charging/regeneration allowing lower limit engine speed value.
Abstract:
In a series-parallel hybrid vehicle, a check is made to see if there is any trouble of a clutch such as slip or overheating in an engaged state of the clutch, and upon detection of a clutch trouble, the vehicle is driven in accordance with a series hybrid type to prevent driving characteristics from being deteriorated by the clutch trouble.
Abstract:
A vehicle electrical system, especially for a motor vehicle, with an APU (auxiliary power unit) based on a fuel cell and a DC/DC converter for converting the DC voltage which is generated by the fuel cell (10) in order to match it to the voltage of the vehicle electrical system, and a process for operating an electrical consumer (14) with electrical power, with which some of the electrical power delivered from the fuel cell (10) is supplied to at least one electrical consumer (14) without conversion by the DC/DC converter (12).
Abstract:
A non-highway vehicle including an engine, a DC power source driven by the engine and providing DC power via a DC bus, a traction motor, a circuit for connection to the DC bus for providing power to the traction motor, and a controller. The circuit includes at least two inverters which share the power supplied to the traction motor. A first inverter connects between the DC bus and the traction motor and a second inverter connects between the DC bus and the traction motor. The second inverter is in parallel connection with the first inverter. The controller coordinates operation of the first and second inverters.
Abstract:
A self-propelled wheelchair (1, 101) comprising a frame (2, 102) supporting a seat (3, 103), two drive wheels (5, 105) mounted to the front of the frame, a prime mover mounted to the frame so as to drive the two drive wheels. The wheelchair having at least one castor wheel (7, 107) mounted to the rear of the frame and pivotal about a substantially vertical axis (Y), the frame being height adjustable in such a manner that when the frame is lowered, the seat is simultaneously tilted backwardly. The frame is provided with an anchoring mechanism (116) which allows the wheelchair to be releasably anchored to an anchoring element (119) secured to the floor.
