摘要:
A braking force control unit, which allows transmission of driving force from a motor to driving wheels irrespective of releasing an accelerator pedal under or equal to a certain vehicle speed when a transmission is selected to a driving range, and switches said driving force to be transmitted to the driving wheels between a strong condition and a weak condition in accordance with depression of a brake pedal such that when the brake pedal is depressed, said driving force is controlled to be less than the driving force upon releasing the brake pedal, wherein the braking force control unit comprises means for retaining braking force so as to continuously retain the braking force after releasing the brake pedal, and said means releases the braking force after releasing the brake pedal and in the process of increasing the driving force to the strong condition.

The invention relates to a method for controlling an automotive vehicle having a first clutch (5) mounted between an engine (1) and a gear drive transmission, for connecting or disconnecting torque transmitted from an engine to driving wheels (22), and torque transmission means (18, 19) disposed between an input shaft (11) and an output shaft (12) of said gear drive transmission, wherein said torque transmission means (18, 19) are of the dog clutch type, and wherein said first clutch (5) is controlled at starting the vehicle or at gear shifting. Said method comprises the steps of, at starting the vehicle, controlling the transmission torque of said first clutch (5) based on a difference between the engine speed and the revolution speed of the transmission input shaft (11) so that the transmission torque of said first clutch (5) is held in a specified range when a difference between the engine speed and the revolution speed of said input shaft (11) has reached a specified value.
摘要:
A transmission system includes a Central Processing Unit (CPU) that controls truck braking energy by sharing energy dissipation between clutch packs. The CPU reduces engine speed and then slips the two clutch packs at the same time to maintain a reduced turbine speed for a torque converter In another aspect of the transmission system, energy loss is reduced during high draw bar pull conditions. The engine speed is modulated to trim energy peaks at low pushing or pulling speeds. An additional transmission gear reduction restores the lost pushing or pulling forces while generating less heat in the torque converter.

In a control apparatus in which a weak creep control for lowering the engaging force of a clutch (5) is performed when a throttle opening (θth) is fully closed, when a brake pedal (BP) is depressed, and when the period of a vehicle speed judging pulse (V pulse) has exceeded a predetermined value TM2s whereby the vehicle is discriminated to be in a stopped condition. Once the weak creep control has started, the weak creep control is stopped by the input of the first V pulse and is transferred to a strong creep control in which the clutch engaging force is increased.

An engine-torque suppression apparatus (101) of a vehicle (1, V) includes an obstacle detection unit (201, 202) configured to detect presence of an obstacle (OBS, OBS') in a traveling direction of the vehicle (1, V), an obstacle-height detection unit configured to detect height of the obstacle (OBS, OBS'), and an engine-torque suppression unit configured to reduce engine torque to be actually generated by an engine below torque corresponding to an accelerator opening under a predetermined condition when presence of the obstacle (OBS, OBS') is detected by the obstacle detection unit (201, 202). The engine-torque suppression unit differentiates a condition for reducing the engine torque depending on the height of the obstacle (OBS, OBS') detected by the obstacle-height detection unit.
摘要:
A motorized vehicle includes a transmission system and an inch/brake device providing at least two ranges of motion. An engagement force of the transmission system is provided in a first range of motion of the inch/brake device, and a braking force of the motorized vehicle is provided in a second range of motion of the inch/brake device. An accelerator device moves between two or more positions, wherein moving the accelerator device from one position to another position causes an amount of overlap between the first and second ranges of motion of the inch/brake device to vary.
