The invention includes a system and method that mediates access to a network of servers hosting a website. A central controller or server is the primary host for client requests, mapping the requests to the appropriate server by redirecting client web requests to the appropriate host server. The status of the server network is constantly monitored by the primary server by periodically “pinging” each of the servers in accordance with standard Internet Protocol (IP.) If a server becomes unavailable, the “down” status is recorded and future client requests for pages hosted by the down server are either immediately issued a user friendly error message or are redirected to an alternate web page on the primary host server or on another available server.

The invention discloses a system for intelligent charging reminding and reservation charging of an electric vehicle. The system comprises a vehicle intelligent terminal, an electric vehicle battery set, an electric vehicle charging station and a cloud computing center; the vehicle intelligent terminal is connected with the electric vehicle battery set and the cloud computing center; and the cloud computing center is connected with the electric vehicle charging station. When the vehicle intelligent terminal of the electric vehicle detects that the remaining electric quantity of the electric vehicle is not sufficient, a voice system of the vehicle intelligent terminal gives an electric quantity alarm to request a driver to conduct charging operation, pushes the travelling distance using the remaining electric quantity to the driver, estimates consumption of the electricity quantity of the distance from the vehicle to all near charging stations, shows the number of unused charging piles of all the near charging stations, and recommends the driver to choose which charging station to charge. According to the system for intelligent charging reminding and reservation charging, the problems that in the prior art, estimation of the remaining electricity quantity and travelling distance is not accurate, and the electric vehicle has no electricity during travelling caused by failing to select the appropriate charging station can be solved.

The present invention provides a method and system for predicting the lateral acceleration of a vehicle, especially a commercial vehicle train. The expected lateral acceleration is used to prevent vehicle rollover during critical driving situations. The expected lateral acceleration is calculated in advance using the vehicle's steering angle and speed, or obtained from a lookup table containing predefined combinations of steering angles and speeds corresponding to lateral acceleration values. The expected lateral acceleration is used in the place of, or in addition to, measured instantaneous lateral acceleration to realize a lead time in which early braking of the vehicle by an electronic stability control system or a rollover stability control system is effected, compared to regulation based on measured lateral acceleration alone.
