Car Switches Help Vehicles Become Intelligent

Nowadays, every automobile manufacturer is facing the challenge of developing electronic networks, which are required to support high bandwidth communication and faster data throughput required for routing data of sensors, controllers and interfaces in electric vehicles, advanced driving assistance systems (ADAS) and autonomous vehicle. The car switch is the backbone of these new systems. Car switches play a key role in the electronic control units of these networks, and their importance is also increasing.

At present, many vehicle manufacturers, system suppliers and chip manufacturers are promoting automobile Ethernet as a new generation of automobile backbone network, which puts forward the following requirements for car switches:

High bandwidth: the current can bus speed only reaches 1Mbps. In the future, the bus speed needs to reach 100Mbps, even 1Gbps, and there is a trend of further improvement. From one hundred megabytes to one gigabyte, it has become a consensus.

Low latency: the new backbone network must meet the millisecond level of latency representation to ensure that time sensitive events succeed in the shortest time without affecting the function representation.

High security and reliability: the car switch needs to withstand the harsh working conditions of the vehicle, meet the requirements of the vehicle level in the impact, vibration, high and low temperature environment, and have strong immunity to electromagnetic interference.

Low cost: compared with the unshielded twisted pair and simple connector structure used in the CAN bus, the new backbone system can not increase significantly in cost.

Lightweight: the car switch shall be designed with miniaturization, small wire diameter and lightweight as much as possible, and the weight of the whole vehicle shall not be excessively increased. This is especially important for this electric vehicle.

As an award-winning and visionary automotive switch supplier, we are committed to providing embedded Internet software products and services for the automotive industry, and providing flexible and innovative solutions for automotive basic software, Internet and security, automatic driving and related tools, and user experience.
