In actual development, the low-speed emergency braking function has high embarkation rate and is closely related to the daily use scene of a client. The low-speed Emergency braking function, namely, the accelerator mis-stepping prevention/automatic Emergency braking function (EAPM), will monitor the obstacles in front and rear of the vehicle in real time. The system automatically brakes to avoid collision with obstacles if necessary.
The system for preventing the accelerator from being stepped on by mistake mainly comprises an intelligent low-speed Brake Support (SCBS) function: when the vehicle is in the process of low-speed forward running or reverse running, automatic braking can be realized to avoid collision when collision with an obstacle is detected.

The predicted Time To Collision (TTC) is calculated from the distance between an obstacle (other vehicle, wall surface, square pillar, etc.) and the vehicle and from the vehicle speed, and the vehicle braking is controlled from the predicted time to collision.
However, during actual use, under certain complex scene conditions, EAPM may malfunction, leading to customer complaints. Particularly, in the case of an underground parking lot, when a vehicle is turned from a slope to a level road during a downhill, a distance sensor in front of the vehicle may misjudge the ground as an obstacle, thereby performing emergency braking, causing a complaint from users.

Detailed Description
The invention is described in further detail below with reference to the figures and specific examples.
Example one
Fig. 4 is a flowchart illustrating a method for controlling a low-speed emergency braking function of an automobile according to the present invention, which includes:
step S401, acquiring the detection gradient of the vehicle;
step S402, if the detected gradient is greater than or equal to a preset first gradient threshold value, the low-speed emergency braking function is inhibited, otherwise;
step S403, if the detected gradient is less than or equal to a preset second gradient threshold value, normally operating a low-speed emergency braking function; wherein:
and when the low-speed emergency braking function is started, the distance between obstacles around the vehicle and the vehicle is detected through a distance sensor, and the vehicle is controlled to brake according to the distance between the obstacles and the vehicle.
Specifically, the present invention can be applied to an Electronic Control Unit (ECU) of a vehicle. The detected gradient of the vehicle is acquired by step S401.
In one embodiment, the obtaining of the detected gradient of the vehicle specifically includes:
if the vehicle is in a downhill state, a downhill gradient of the vehicle is detected as a detected gradient of the vehicle.
When the vehicle is detected to incline downwards, the vehicle can be judged to be in a downhill state, the inclination of the vehicle can be obtained through the inclination sensor of the vehicle, and the inclination of the vehicle is the detection gradient of the vehicle in the downhill process.
The invention adjusts the low speed emergency braking function based on the detected grade. When the detected gradient is greater than the first gradient threshold, step S402 is executed to inhibit the low-speed emergency braking function and avoid that a slope with a large gradient is mistakenly considered as an obstacle to trigger braking of the vehicle. When the detected gradient is smaller than the second gradient threshold, step S403 is executed, and the low-speed emergency braking function is normally operated without being inhibited. The second grade threshold may be equal to or less than the first grade threshold. Preferably, the first slope threshold is 8 ° and the second slope threshold is 6 °. If the second gradient threshold is less than the first gradient threshold, when the detected gradient is greater than the first gradient threshold, step S402 is executed to enter the gradient mode and suppress the low-speed emergency braking function. When the detected grade is between the first grade threshold and the second grade threshold, the current mode of the vehicle is not changed. When the detected gradient is less than the second gradient threshold, step S403 is performed to resume the normal mode.
According to the invention, the low-speed emergency braking function is inhibited when the vehicle is on the slope, so that the low-speed emergency braking function is prevented from starting braking due to the fact that the flat ground is mistakenly triggered as an obstacle when the vehicle is on the slope, and the use experience of a user is improved.

step S602, if the detected gradient is greater than or equal to a preset first gradient threshold, suppressing a low-speed emergency braking function, where the suppressing the low-speed emergency braking function specifically includes: forbidding the low-speed emergency braking function, otherwise;
step S603, if the detected gradient is less than or equal to a preset second gradient threshold value, normally operating a low-speed emergency braking function; wherein:
the second gradient threshold value is smaller than or equal to the first gradient threshold value, when the low-speed emergency braking function is started, the distance between obstacles around the vehicle and the vehicle is detected through an ultrasonic sensor, the vehicle is controlled to brake according to the distance between the obstacles and the vehicle, the height between the ultrasonic sensor and the ground is 40 cm-60 cm, and the pitch angle of the ultrasonic sensor is 4-8 degrees of upward inclination.
Preferably, the height of the ultrasonic sensor from the ground is 50 to 55 cm, and the pitch angle of the ultrasonic sensor is 6 degrees.
The height between the ultrasonic sensor and the ground is increased or the pitch angle of the ultrasonic sensor is raised upwards. The height between the ultrasonic sensor and the ground is increased, so that the detection range of the ultrasonic sensor is increased, and the ground is prevented from being triggered as an obstacle by mistake when the slope goes downhill. And the pitch angle of the ultrasonic sensor is raised upwards, so that the detection direction of the ultrasonic sensor is inclined upwards, and the ground is prevented from being triggered as an obstacle by mistake when the slope goes downhill.
The low-speed emergency braking prohibition function is to completely stop the use of the low-speed emergency braking function. However, in addition to completely disabling the low-speed emergency braking function, various parameter thresholds of the low-speed emergency braking function may be adjusted to accommodate the slope conditions.
In one embodiment, the suppressing the low-speed emergency braking function specifically includes:

controlling the pitch angle of the distance sensor to be the sensor angle;
and detecting the distance between the obstacle around the vehicle and the vehicle based on the adjusted distance sensor, and controlling the vehicle to brake according to the distance between the obstacle and the vehicle.
This embodiment selects the sensor angle that corresponds to different detection slopes to make distance sensor's the pitch angle correspond different detection slopes, adapt to different slope slopes through adjustment distance sensor's pitch angle, in order to avoid the spurious triggering. The specific correspondence may be calibrated by actual measurement. The distance sensor may be provided on a rotatable rotary base, and the rotation of the rotary base is driven by a motor to change the pitch angle of the distance sensor.
In one embodiment, the sensor angle corresponding to a larger detection slope is greater than or equal to the sensor angle corresponding to a smaller detection slope.

controlling the height of the distance sensor to be the sensor height;
and detecting the distance between the obstacle around the vehicle and the vehicle based on the adjusted distance sensor, and controlling the vehicle to brake according to the distance between the obstacle and the vehicle.
Specifically, the slope on which the vehicle is located is calculated based on the vehicle speed and the longitudinal acceleration of the vehicle.
This embodiment selects corresponding sensor height to different detection slopes to make distance sensor's height correspond different detection slopes, adapt to different slope slopes through adjustment distance sensor height, in order to avoid the spurious triggering. The specific correspondence may be calibrated by actual measurement. The distance sensor can be arranged on a lifting base capable of ascending and descending, and the motor drives the lifting base to ascend and descend so as to change the height of the distance sensor.

The specific correspondence may be calibrated by actual measurement.

Then, according to different road surface types, a corresponding first gradient threshold value and a corresponding second gradient threshold value are selected.
According to the embodiment, the corresponding first gradient threshold value and the corresponding second gradient threshold value are selected according to different road surface types, so that different slope road surfaces can be better adapted.
