Embodiment Construction

[0028] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0029] Such as figure 1 As shown, the vehicle assisted driving control platform is generally composed of the underlying hardware platform U1 and the upper layer software architecture U2. The hardware platform U1 is constructed by a heterogeneous, multi-core SOC system-on-chip, that is, a microprocessor or microcontroller architecture containing two or more different types of cores. Embedded with different performance ARM core, DSP core, GPU, proprietary image processing engine, etc. Different cores process different transactions according to performance requirements, and communicate through inter-core communication to meet the high-speed, low-latency, real-time, and security features of ADAS technology and V2X communication. The SOC chip (referred to as the main control chip in this embodiment) belongs to conventional technology, and the specific chip model...

Abstract

The invention relates to a vehicle assisted driving control platform, which comprises a main control chip, wherein the main control chip is an SOC (System On Chip) with heterogeneous multi-core architecture, the SOC is further provided with a video processing unit, a display output unit and a communication unit in addition to a main control unit, and the SOC is also provided with corresponding data interfaces. The high-performance SOC with the heterogeneous multi-core architecture is selected to establish an ADAS technology platform, the overall operation performance of a processor is improvedby applying a concurrent processing mode, collaboration is performed under the premise of ensuring low delay and low power consumption, and thus various active security functions are realized in an integrated manner by the same processor, so that reliable driving assistance control can be performed reliably by using the high-integration SOC. In addition, various processors are integrated by the high-performance processor through a method of platform establishment, thereby solving a problem that single-core processors and processors of a decentralized independent system are low in processing capacity, slow in processing speed, single in system structure and the like.

Description

technical field [0001] The invention relates to a vehicle auxiliary driving control platform, which belongs to the technical field of vehicle auxiliary driving control. Background technique [0002] Advanced Driver Assistance System (ADAS) has been gradually applied in the field of vehicle safety control to improve the auxiliary safety level of vehicle driving. Limited by the performance of the processor, ADAS technology was originally focused on realizing a single function. With the rapid development and replacement of the semiconductor era, the current ADAS technology is gradually moving towards the construction of an integrated, high-performance, and computing-intensive SOC system. Developed in the direction of focusing on the integrated control system, by fusing multi-sensor environmental information, it can cover a series of functions such as lane departure and collision warning, blind spot detection, panoramic view, traffic sign recognition, and pedestrian detection. ...
