Title:
STEEP SLOPE SLOW DESCENDING SYSTEM FOR VEHICLE AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2018/045881
Kind Code:
A1
Abstract:
A steep slope slow descending system (100) for a vehicle and a control method therefor. The steep slope slow descending system (100) comprises: a plurality of wheels (2); a plurality of wheel speed sensors (10), which correspond to the plurality of wheels (2) and which are used for detecting speeds of the plurality of wheels (2); a plurality of motors, which correspond to the plurality of wheels (2) and which are used for selectively driving and braking the plurality of wheels (2); a plurality of motor controllers (4), which are respectively connected to the plurality of motors (3) and which are used to control operation states of the plurality of motors (3); a plurality of gyro sensors (11), which correspond to the plurality of motors (3) and which are used for detecting rotation speeds of the plurality of motors (3); and a whole vehicle controller (1), which is connected to the plurality of wheel speed sensors (10), the plurality of motor controllers (4) and the plurality of gyro sensors (11), respectively, and which is used, according to the speeds of the plurality of wheels (2) and the rotational speeds of the plurality of motors (3), to determine an actual slope descending speed of the vehicle and control the plurality of motor controllers (4) according to the actual slope descending speed of the vehicle so as to adjust the operation states of the plurality of motors (3).
