Detailed Description
The following detailed description of the embodiments of the present invention will be given in order to provide those skilled in the art with a more complete, accurate and thorough understanding of the inventive concept and technical solutions of the present invention.
Fig. 1 shows a flowchart of the present invention, which is a method for identifying a climbing condition of a hybrid vehicle. In order to overcome the defects of the prior art and achieve the purpose of eliminating potential safety hazards during long-slope climbing, the invention adopts the technical scheme that:
as shown in fig. 1, the method for identifying a climbing condition of a hybrid electric vehicle according to the present invention includes the steps of:
1) judging the ramp state of the whole vehicle according to the gradient signal after the strong current is applied to the whole vehicle; if the gradient is larger than or equal to the set gradient of the climbing working condition flag bit, entering the step 2); if not, executing according to a conventional hybrid control program;
2) judging the running state of the vehicle;
if the vehicle is in a pure electric and static state, the engine is not started, and the engine is started when the vehicle speed reaches 10 kph;
if the hybrid state is adopted, the engine is controlled not to be flamed out, and meanwhile, the battery is ensured to be in a rapid charging state through the calibrated engine torque, so that the SOC is rapidly charged to be more than 0.5;
it should be noted that the hybrid transmission has a clutch characteristic, so that the operating point of the engine should be selected to avoid the relatively severe operating condition of the clutch.
3) After the grade climbing working condition flag bit is established, the P/D gear strategy is as follows:
when the following conditions are met, the P-gear climbing condition flag bit is established:
(1) the SOC of the battery is kept to be higher than 30%;
(2) the signal of an accelerator pedal is less than 30 percent;
(3) when the water temperature of the engine is higher than 30 ℃, the engine is not started, and the whole vehicle is in a pure electric state.
The identification strategy for the working condition of climbing a long slope can effectively solve the problem that the torque output of the motor is influenced by the power battery power feeding caused by the continuous discharge of the power battery when the hybrid electric vehicle climbs the long slope in the conventional driving working condition, and eliminates potential safety hazards.
Under the following working conditions, the D-gear climbing working condition flag bit is established:
(1) pure electric starting working condition: the large throttle engine is not started, the engine is started when the vehicle speed rises to be near 10kph, the working point of the engine is calibrated, the power battery is rapidly charged, and the rotating speed and the torque of the engine with serious Rabtle are avoided;
(2) and mixed-motion running working condition: forbidding the engine to stop, and adjusting the rotating speed and the torque of the engine to ensure that the power battery is in a charging or non-charging and non-discharging state;
(3) and the gradient is less than 10 percent, the SOC is more than 0.5, and the engine is allowed to stop after the duration of 3 min.
The grade climbing condition flag bit judgment conditions are as follows:
1) EPB or ESP fed back grade signal;
2) integral number T calculated inside vehicle controllerR(integral of vehicle required torque) and
Figure BDA0002828390470000041
(vehicle speed integral).
After the grade climbing condition flag bit is established, in order to ensure the normal work of the system, the following logic processing is carried out:
1) in a short time that the slope starting acceleration working condition is allowed for 15s, the battery discharge power exceeds about 10% of the battery allowed discharge power; at the moment, the SOC is allowed to be about 20% on the premise of not causing serious damage to the power battery;
2) after the gear R is shifted, clearing the flag bit of the climbing working condition (because the reversing requirement can be met after climbing to a certain gradient, the reversing power of the HEV is poor, and the HEV cannot ascend a large slope, clearing the flag bit of the climbing working condition after the gear R is shifted);
3) identifying the current climbing slope: setting a climbing working condition flag bit when the gradient is more than 10% and lasts for 3 seconds; due to the accuracy of slope calculation, the situation that the slope is less than 10% may occur at one time, so that the position of the slope climbing working condition mark is delayed.
4) Calculating the slope, and giving the slope value at the previous moment when the slope cannot be determined; the calculated gradient is continuous and uninterrupted.
5) On a slope, if only the accelerator is released, the brake torque is not output, but the driving torque is always supplied;
6) and when the gradient is larger than 15%, if the SOC is larger than the standard quantity and the vehicle speed is smaller than 1kph, controlling the engine to stop.
The invention has been described above with reference to the accompanying drawings, it is obvious that the invention is not limited to the specific implementation in the above-described manner, and it is within the scope of the invention to apply the inventive concept and solution to other applications without substantial modification.
