Embodiment 1

[0022] When the rocker switch is pressed, the E mode is triggered. In the E mode, the embedded processor judges the current working condition according to the vehicle speed information input by the CAN communication module and the vehicle acceleration information calculated from it. When the vehicle speed and acceleration are greater than the set value, And the embedded processor judges the timing of triggering the limit mode according to the current engine torque and speed information input by the CAN communication module, and when the actual torque and speed are close to the torque limit and speed limit setting range, the speed limit and torque limit modes are triggered. When it is determined to be a rapid acceleration and high fuel consumption condition, the embedded processor starts to send the engine speed limit request and torque limit request to the CAN of the vehicle through the CAN communication module to limit the engine speed, torque change rate and maximum torque val...

Abstract

The invention discloses a vehicular energy-saving electric control device and a control method thereof. The device comprises a power module, a CAN communication module, an embedded processor and a rocker switch. The control method includes: step one, the embedded processor reads E and P state information of the rocker switch; step two, the embedded processor sets corresponding engine rotating speed limiting values and torque limiting values according to different operating conditions, and when an E mode is triggered and the vehicle speed is lower than a set limiting value, a limiting mode is not triggered so as to guarantee the starting performance of a vehicle; step three, when the E mode is triggered, the vehicle acceleration is larger than a set value and the engine practical rotating speed and torque are smaller than limiting value setting ranges, a rotating speed limiting and torque limiting mode is triggered, and the embedded processor starts to send an engine rotating speed limiting request and a torque limiting request to an integral vehicle CAN through a CAN communication module. By optimization of vehicular power system response characteristics, a control system is provided for avoiding risky driving behaviors and improving fuel economy.

Description

technical field [0001] The invention relates to a vehicle energy-saving electric control device, more specifically relates to a vehicle energy-saving electric control device and a control method thereof, belonging to the technical field of automobile control systems. Background technique [0002] At present, under the influence of various pressures such as energy conservation, environmental protection and market competition, it is imperative to enhance the core competitiveness of automobile products. Fuel economy is an important factor in the core competitiveness of automobiles. Therefore, improving vehicle fuel economy has become the top priority of current automobile design and manufacturing technology. [0003] Optimizing driving behavior is an effective way to improve vehicle fuel economy. At this stage, optimizing driving behavior is mainly achieved through fuel-saving driving training or vehicle fuel-saving driving reminder systems; Avoid the driver's violent driving ...
