Embodiment Construction
[0063] The technical solution of the present invention will be further described in detail below in conjunction with the embodiments and the accompanying drawings.
[0064] Such as figure 1 Shown is the installation structure diagram of the embodiment of the present invention, the level sensor 1 is installed on the top of the vehicle, and is used to measure the forward tilt angle and the roll angle of the vehicle.
[0065] The hydraulic cylinder stroke sensor includes a rocker arm hydraulic cylinder stroke sensor 2 and a boom hydraulic cylinder stroke sensor 3, which are used to measure the rocker arm hydraulic cylinder displacement and the boom hydraulic cylinder displacement respectively.
[0066] The tire force sensor 4 is a one-dimensional force sensor installed at the center of the tire for measuring the lateral force and vertical force suffered by the tire.
[0067] The bending angle sensor 5 is an angle sensor, which is installed at the hinge point position of the fron...

The invention discloses a loading machine turnover preventing control system and method. The system comprises a side inclination preventing controller, a gradienter sensor, hydraulic cylinder stroke sensors, a bowing angle sensor, tire force sensors, a hydraulic locking system, a transmission control system, a brake control system and an alarm device, wherein the gradienter sensor, the hydraulic cylinder stroke sensors, the bowing angle sensor, the tire force sensors, the hydraulic locking system, the transmission control system, the brake control system and the alarm device are connected withthe controller. The control method includes the steps that the change conditions of a rear vehicle frame design gravity center, a front vehicle frame gravity center and a bucket geometric gravity center along with the hydraulic cylinder strokes are calculated through three-dimensional design software, the hydraulic cylinder stroke sensors are used for assisting in calculating a vehicle gravity center, the side inclination stability index of a loading machine in the working process is monitored in real time through all the sensors and the controller, when the monitored index reaches a threshold value, the alarm device gives an alarm, certain measures are taken through the hydraulic locking system, the transmission control system and the brake control system for a working system and a traveling system, and turnover preventing control measures at different emergency levels are taken. The system and method have the beneficial effects that detection is sensitive, cost is low, and universality is high.
Description
technical field [0001] The invention relates to a vehicle control system and a control method, in particular to a loader anti-overturn control system, and also relates to an anti-overturn control method. Background technique [0002] Wheel loaders are engineering vehicles with a wide range of applications and a huge amount of applications. During the use of loaders, especially in mines, steep slopes, trenches, hills and other irregular terrain conditions, tipping accidents account for a large proportion of wheel loader accidents. Overturning accidents mainly include side overturning and front and rear overturning. In overturning accidents, side overturning is the most likely to occur. Moreover, the operation level of the loader operators is uneven, and necessary protective measures need to be taken to protect the safety of the workers, and at the same time reduce the education costs of the operators. [0003] Rollover protection measures for wheel loaders include passive p...
