VEHICLE SPEED CONTROL DEVICE FOR INDUSTRIAL VEHICLE
A vehicle speed control device for an industrial vehicle is configured to control a vehicle speed of the industrial vehicle. The vehicle speed control device includes an operation detector that is configured to detect whether an accelerator pedal is being operated and a controller that is configured to control the vehicle speed of the industrial vehicle by controlling the rotation speed of the engine. The controller is configured to derive a vehicle speed limit value that increases during an operated state of the accelerator pedal and decreases during a non-operated state of the accelerator pedal, and set an upper limit value of the vehicle speed to the derived vehicle speed limit value.
VEHICLE ASSISTANCE CONTROL APPARATUS
A vehicle assistance control apparatus includes: an obstacle detection unit that detects a prescribed obstacle in the periphery of a vehicle; a vehicle speed detection unit that detects a speed of the vehicle; an accelerator operation detection unit that detects presence of an accelerator operation; a drive power restriction unit that detects, when the prescribed obstacle is detected, a drive power that is to be generated in the vehicle by an accelerator operation performed by a driver, compared to when the prescribed obstacle is not detected; and a cancellation unit that enables cancellation of the restriction of the drive power by the drive power restriction unit, when the speed is equal to or lower than a prescribed value and when a state where the accelerator operation detection unit detects that the accelerator operation is not being performed has continued for a prescribed period of time or longer.
VEHICLE DRIVE ASSIST SYSTEM AND VEHICLE DRIVE ASSIST METHOD
An automatic following control execution unit recognizes a preceding vehicle of the own vehicle and performs automatic following control of causing the own vehicle to automatically follow the preceding vehicle. A start-command acquisition unit acquires a start command to initiate the automatic following control. An automatic following control starting unit starts the automatic following control, when the brake is switched from on to off after satisfaction of a first to fifth conditions. The first condition is that the own vehicle is not under the automatic following control. The second condition is that a brake of the own vehicle is in an on state. The third condition is that the own vehicle is at rest. The fourth condition is that the preceding vehicle has been recognized. The fifth condition is that the start command acquisition means has acquired the start command. A target stopping inter-vehicle distance setting unit detects a first inter-vehicle distance between the own vehicle and the preceding vehicle when the first to fifth conditions are satisfied, and sets, as the first inter-vehicle distance, a target inter-vehicle distance for stopping the own vehicle. A start timing setting unit detects a second inter-vehicle distance between the own vehicle and the preceding vehicle at the start of the automatic following control, and sets a start timing for starting the own vehicle on the basis of the second inter-vehicle distance.
Vehicle transmission apparatus
A vehicle transmission apparatus having a starting engagement friction element, which has friction plates and a hydraulic servo including a piston that is moved according to a supplied oil pressure to press the friction plates, which is controlled to be engaged when a vehicle is started by using at least a driving force of the internal combustion engine, and which transfers creep torque. A control device capable of receiving an accelerator operation amount signal and capable of outputting a command value that controls the oil pressure. The control device executes temporary increase control of temporarily increasing the command value, when the accelerator operation amount signal is turned on from a state where the accelerator operation amount signal is off and the command value is output so that the starting engagement friction element transfers the creep torque.
METHOD FOR PRESENTING INFORMATION UPON STARTING AN AUTOMOTIVE VEHICLE
A method for presenting information upon starting an automotive vehicle includes at least one step in which various parameters associated with the vehicle are verified. Also included is a step in which a particular light beam is projected onto a specific area of the passenger compartment of the vehicle when the state of a plurality of verified parameters allows the vehicle to be started.
Method for improving startability of a vehicle
A method for improving startability of a vehicle is provided, the vehicle being provided with a prime mover and a kinetic energy recuperation system. The prime mover is adapted to propel the vehicle either alone or in combination with the kinetic energy recuperation system which is operably coupled to the prime mover and to wheels of the vehicle and is adapted to store energy at times when there is an abundance of energy and to use energy at times when there is a demand for energy. A vehicle is also provided. The method includes determining that the vehicle is standing still or essentially standing still; detecting a take-off assistance condition; detecting a level of energy in the kinetic energy recuperation system; if the level of energy is found insufficient, connecting the prime mover to the kinetic energy recuperation system and running the prime mover such that energy from the prime mover is stored in the kinetic energy recuperation system; and when a driver requests the vehicle to take off, running the prime mover and consuming energy from the kinetic energy recuperation system such that the wheels of the vehicle initiate propelling thereof.
Anti-jerk method
A method for damping juddering in the drive train of a vehicle having an electric motor as the drive motor, and a vehicle having a closed-loop control system to carry out the method. The method includes calculating an electric motor setpoint torque for actuating the electric motor from an electric motor request torque which corresponds to a current request for a torque, and calculating a correction torque as a function of the electric motor request torque and a correction factor which is determined from a rotational speed of the electric motor.
SYSTEMS AND METHODS FOR MANAGING TORQUE
A method of managing torque at a vehicle standstill includes outputting torque from a powertrain to satisfy a driver torque demand. The method also includes, in response to a nonzero torque demand resulting in vehicle standstill, applying a friction brake to maintain the vehicle standstill and substantially reducing output torque of the powertrain during friction brake application. The method further includes satisfying driver torque demand using the powertrain and releasing the friction brake in response to the driver torque demand deviating from the nonzero torque demand by more than a predetermined amount.
Engine starting apparatus
In an engine starting apparatus, a starter control unit is configured to, upon command to start the engine, put a starter in a drive ON state to begin cranking of the engine and then put the starter in a drive OFF state at a predetermined timing. The starter control unit is configured to, when acceleration is requested within a predetermined time period from the command to start the engine, keep the starter in the drive ON state even after the time when the starter would be put in the drive OFF state without the acceleration request within the predetermined time period, and drive the starter to torque-assist the engine, thereby performing an assist mode in which both the engine) and the starter serve as drive sources for driving a vehicle.
Shift control method for preventing starting stage engagement failure of hybrid electric vehicle
When a hybrid electric vehicle in which an automatic manual transmission (AMT) is equipped stops and then re-starts, when a starting stage of the AMT is not implemented, an RPM of a driving motor which is directly connected to an input shaft is changed so that a torque applied to an input shaft of the AMT is increased or decreased, and thus even though a blocking phenomenon occurs when an AMT-HEV stops and then re-starts after an engine re-starts, the torque transferred from the driving motor to the input shaft is appropriately increased and decreased and thus a gear restricted to the input shaft differently rotates from a synchronizer.
