Abstract

The invention discloses a car direction sensor and a car, and belongs to the technical field of sensors. The car direction sensor comprises a connecting structure, a transmission assembly and a data sensing assembly; a third gear and a second gear of the transmission assembly are nested with each other; the inner hole of the third gear is in sliding fit with a first mandrel; the second gear is engaged with a first gear of the connecting structure; the diameter of a reference circle of the third gear is smaller than that of a reference circle of the second gear; and the diameter of the reference circle of a fourth gear is greater than that of a reference circle of the third gear. The car direction sensor disclosed by the invention is compact in structure and can intuitively and quickly carry out data origin calibration. The car direction sensor disclosed by the invention adopts a non-contact and digital transmission way, and has the characteristics of being long in service life, high in measuring precision, great in data transmission distance and free of interference. The car direction sensor can provide powerful technical support for implementing car intelligent emerging technologies such as a car automatic brake AEB system or car automatic driving.

Description

technical field [0001] The invention relates to the technical field of sensors, in particular to an automobile direction sensor used in automobile automatic braking and automobile automatic driving technologies. Background technique [0002] Automatic emergency braking system (AEB, Automatic Emergency Braking) is an active safety technology for automobiles. The system relies on sensors to monitor the target in front and detect the relative speed and distance to the target, calculate the situation that is about to happen, and Automatically adopt emergency braking to avoid or reduce collisions under certain circumstances. This system has become another new core technology leading the upgrading of the world's automobile industry. Euro-NCAP (European New Car Safety Appraisal Association), the world's most authoritative automobile safety inspection organization, has added AEB as a bonus item for 5-star evaluation in the 2014 automobile safety inspection and evaluation regulations...
