Problems solved by technology

The shifting process of these vehicles is relatively long, about 3 to 5 seconds. Shifting gears during the uphill process will not only lead to a sharp drop in vehicle speed, but if the shifting is not timely, it will easily cause the engine to stall, which not only reduces efficiency, but also causes the vehicle to slide downhill. security risks

Abstract

The invention relates to the technical field of engines of heavy vehicles, and discloses upslope-climbing-assisting torque improving equipment for an engine of a heavy vehicle. The upslope-climbing-assisting torque improving equipment comprises an ECU used for controlling the engine, a tilt angle sensor and an equipment terminal, wherein the tilt angle sensor is arranged in the equipment terminal; the equipment terminal is connected with the ECU through a low-speed CAN bus and a high-speed CAN bus; the tilt angle sensor is used for measuring the included angle between the tilt angle sensor and the level plane and the accelerated speed of the tilt angle sensor relative to the ground. The invention further discloses a method for improving the upslope-climbing-assisting torque of the engine through the upslope-climbing-assisting torque improving equipment for the engine of the heavy vehicle. The torque of the engine can be improved properly when the heavy vehicle climbs an upslope, so that the operating efficiency of the vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of heavy-duty vehicle engines, in particular to a heavy-duty vehicle engine uphill assist torque boosting device and a lifting method. Background technique [0002] Heavy-duty commercial vehicles, especially tractors and dump trucks, generally operate in an overloaded state, with a load of about 50t, and some are even heavier. The shifting process of these vehicles is relatively long, about 3 to 5 seconds. Shifting gears during the uphill process will not only lead to a sharp drop in vehicle speed, but if the shifting is not timely, it will easily cause the engine to stall, which not only reduces the efficiency, but also causes the vehicle to slide downhill. security risks. Contents of the invention [0003] (1) Technical problems to be solved [0004] The technical problem to be solved by the present invention is how to properly increase the engine torque when the heavy vehicle goes uphill, so as to imp...
