First, an application scenario of the present disclosure is explained, and the present disclosure may be applied to a scenario in which exhaust temperature of a vehicle is controlled, in which exhaust gas generated by operation of an engine is discharged through a tail pipe during driving of the vehicle, if a distance between a rear adjacent vehicle and the vehicle is small, the exhaust gas discharged by the vehicle may affect the rear adjacent vehicle, for example, if the temperature of the discharged exhaust gas is high, in a case that the front and rear distances are small, a bumper of the rear adjacent vehicle may be deformed, thereby affecting driving safety of the rear vehicle, and there is a great risk.

Among the prior art, generally cool down exhaust waste gas through increasing the heat sink, thereby reduce exhaust gas temperature, for example increase the cooling water jacket on tail pipe, reduce the blast pipe temperature through the coolant liquid, thereby reduce the temperature of exhaust waste gas, however, the inventor discovers, under the condition that the engine is in the continuous working phase, can continuously produce high temperature waste gas, and the coolant liquid needs certain response time to the reduction of tail pipe temperature, lead to the unable timely cooling of the high temperature waste gas that continuously produces, it is thus visible, carry out the scheme of cooling to the exhaust through the heat sink at present, cooling response time is longer, the cooling effect is relatively poor, can't avoid the influence to back car safety.

In order to solve the above problems, the present disclosure provides a method, an apparatus, an electronic device, and a vehicle for controlling an engine, where the method can control the engine to stop generating power when a distance between vehicles coming from a rear is too short, so as to stop discharging high-temperature exhaust gas, and thus, there is no influence on the vehicles coming from the rear, and an effect of temporarily and rapidly reducing an exhaust temperature is achieved.

The present disclosure is described below with reference to specific examples.

Fig. 1 is a method for controlling an engine according to an embodiment of the present disclosure, as shown in fig. 1, the method includes:

s101, the distance between the vehicle and the adjacent vehicle behind is obtained.

The battery power of the vehicle can be acquired first, and the distance between the vehicle and the rear adjacent vehicle is acquired when the battery power is greater than or equal to a first preset power threshold and less than or equal to a second preset power threshold.

The battery power is the power of the vehicle power battery, and when the battery power is smaller than the first preset power threshold, it indicates that the power of the power battery is insufficient, and if the power battery is continuously used, it may cause power shortage or even damage of the power battery, and seriously affect the service life of the power battery, so that the engine needs to be controlled to generate power to charge the power battery, thereby ensuring that the power battery is not affected, for example, the first preset power threshold may be set to 20% -30% of the total power of the vehicle power battery, such as 20%, 30%, or 40%. And in the case that the battery power is greater than a second preset power threshold, the battery power is sufficient, and the power battery does not need to be charged, and the engine is controlled to stop generating power, for example, the second preset power threshold may be 70% to 90% of the total power of the vehicle power battery, such as 70%, 80%, or 90%. When the battery power is greater than or equal to the first preset power threshold and less than or equal to the second preset power threshold, it indicates that the power battery can be used without being charged and without causing damage to the power battery, that is, when the battery power is greater than or equal to the first preset power threshold and less than or equal to the second preset power threshold, the engine can be charged, and the charging can also be stopped.

In addition, a temperature sensor can be arranged at the tail pipe of the vehicle to acquire the exhaust temperature; under the condition that the battery power is greater than or equal to a first preset power threshold and less than or equal to a second preset power threshold, acquiring the distance between the vehicle and a rear adjacent vehicle comprises: when the battery power is greater than or equal to a first preset power threshold, and less than or equal to a second preset power threshold, and the exhaust temperature is greater than or equal to a preset temperature threshold, the distance between the vehicle and a rear adjacent vehicle is obtained, for example, the preset temperature threshold may be 80 ℃ to 120 ℃, such as 80 ℃, 100 ℃, or 120 ℃.

It should be noted that, the first preset electric quantity threshold is 20% -40% of the total electric quantity of the vehicle power battery, and the second preset electric quantity threshold is 70% -90% of the total electric quantity of the vehicle power battery, which is only an example, and the disclosure is not limited thereto, and the actual electric quantity threshold may be preset according to different vehicle types and battery capacities.

Under the condition that the battery electric quantity is greater than or equal to a first preset electric quantity threshold value and is less than or equal to a second preset electric quantity threshold value, the distance between the vehicle and the rear adjacent vehicle can be acquired through a distance measuring sensor arranged on the vehicle, and therefore the distance can be accurately acquired.

Wherein, above-mentioned range sensor includes: radar ranging sensor, infrared ranging sensor or laser ranging sensor, this ranging sensor can be one or more, and this ranging sensor's quantity and kind can be selected and use according to actual conditions, do not do the restriction here, exemplarily, can set up a ranging sensor respectively at vehicle afterbody left and right sides both ends, acquire the distance of this vehicle and the adjacent vehicle in rear through this ranging sensor to improve distance detection's accuracy.

And S102, controlling the engine of the vehicle to stop generating power under the condition that the distance is smaller than or equal to the preset distance threshold value.

The distance is smaller than or equal to a preset distance threshold, which indicates that the vehicle is closer to a rear adjacent vehicle, for example, the preset distance threshold may be 0.5m to 1m, such as 0.5m, 0.7m, 1m, and the like, and high-temperature exhaust gas emitted by the vehicle may affect a bumper of a rear vehicle, so that it is necessary to control the engine of the vehicle to stop generating power to reduce the exhaust temperature, for example, the engine of the vehicle may be controlled to be in an idle state, or the engine may be controlled to stop operating. Through the steps, when the distance between the vehicle and the rear adjacent vehicle is too short, the influence of the discharged high-temperature waste gas on the rear adjacent vehicle bumper is avoided, and potential safety hazards are eliminated.

Adopt above-mentioned scheme, can be according to vehicle battery's residual capacity and the distance with the adjacent vehicle in rear, stop the high temperature waste gas of discharging in the short time, eliminate the influence that high temperature exhaust comes the car to the rear, solved high temperature exhaust and led to the fact the problem of influence to the adjacent vehicle in rear, promote the security performance, this disclosure need not to increase extra device in addition, the realization process is simpler, and realizes that the cost is lower.

if the power is less than the first preset power threshold, step S210 is executed.

And under the condition that the electric quantity of the battery is smaller than the first preset electric quantity threshold value, the electric quantity of the vehicle battery is lower, the vehicle battery needs to be charged by power generation of an engine, otherwise, the battery can be damaged.

If the distance is less than or equal to the preset distance threshold, performing steps S208 and S209;

in case the distance is greater than the preset distance threshold, step S210 is performed.

The preset distance threshold is a minimum distance that the high-temperature exhaust of the exhaust pipe does not affect the rear adjacent vehicle, for example, the preset distance threshold may be 0.5m to 1m, such as 0.5m, 0.7m or 1m, taking the preset distance threshold as 0.7m as an example, when the distance between the rear adjacent vehicles is greater than 0.7m, the high-temperature exhaust will be rapidly cooled in the air, and cannot affect the rear adjacent vehicles; under the situation that the distance between the rear adjacent vehicles is less than or equal to 0.7m, the high-temperature exhaust of the exhaust pipe cannot be cooled in the air, certain influence on the rear adjacent vehicles can be caused, and potential safety hazards exist.

And S208, sending out alarm information.

And S209, controlling the engine of the vehicle to stop generating power.

And under the condition that the electric quantity of the battery is greater than a second preset electric quantity threshold value, the electric quantity of the vehicle battery is sufficient, the vehicle battery does not need to be charged, and the engine can be controlled to stop generating electricity, such as the engine is controlled to be in an idle state or stop working.

Under the condition that the engine stops generating power, the high-temperature exhaust gas stops being discharged, so that any influence on the adjacent vehicles behind is avoided, and potential safety hazards are eliminated.

And S210, controlling the engine to generate power.

Illustratively, taking the first preset electric quantity threshold value as 30%, the second preset electric quantity threshold value as 80%, the preset temperature threshold value as 100% and the preset distance threshold value as 0.7m as an example, when the vehicle is in a driving state, the electric quantity of the battery of the vehicle is acquired, when the electric quantity is less than 30%, the electric motor of the vehicle is controlled to generate electricity while continuously acquiring the electric quantity of the battery, when the electric quantity is greater than 80%, the electric motor of the vehicle is controlled to stop generating electricity while continuously acquiring the electric quantity of the battery, when the electric quantity of the battery of the vehicle is greater than or equal to 30% and less than or equal to 80%, the exhaust temperature of the exhaust pipe is acquired, and the exhaust pipe of the vehicle is provided with a temperature sensor, and the acquiring of the exhaust temperature comprises: under the condition that the exhaust temperature is greater than or equal to 100 ℃, the distance between the vehicle and a rear adjacent vehicle is obtained, whether the engine is controlled or not is judged according to the distance between the vehicle and the rear adjacent vehicle, under the condition that the distance is less than or equal to 0.7m, warning information is sent out firstly to remind a driver of paying attention to safe and careful driving, meanwhile, in order to eliminate potential safety hazards caused by the influence of high-temperature tail gas on the rear adjacent vehicle, the engine of the vehicle is controlled to stop power generation, under the condition that the distance is greater than 0.7m, the high-temperature tail gas can be rapidly cooled in the air, the influence on the rear adjacent vehicle is avoided, and the engine is controlled to generate power; under the condition that the exhaust temperature is lower than 100 ℃, any influence on the adjacent vehicle behind cannot be caused, the distance between the adjacent vehicle behind and the adjacent vehicle behind is not acquired, and the engine is controlled to generate electricity.

It should be further noted that, the first preset electric quantity threshold is 80% of the total electric quantity of the vehicle battery, the second preset electric quantity threshold is 30% of the total electric quantity of the vehicle battery, the preset temperature threshold is 100 ℃, and the preset distance threshold is 0.7m, which are only examples, and in an actual situation, the preset temperature threshold may be preset according to an empirical value or a test value, which is not limited in the present disclosure.
