The present invention provides a method and system for segmentally limiting the speed of a vehicle. The method comprises: receiving characteristic parameters of a route sent by a vehicle monitoring platform, and respectively expanding a plurality of road segments of the route into a plurality of rectangles; dividing the plurality of rectangles into blocks sequentially; calculating a minimum enclosing rectangle of the at least two rectangles, and counting vertex information of the minimum enclosing rectangle of each block so as to establish a hash table; obtaining an instant longitude and latitude of a moving vehicle, searching in the hash table so as to determine a block where the vehicle is located, and judging a road segment where the vehicle is currently located; and comparing a current speed of the vehicle with a limiting speed of the road segment where the vehicle is currently located, judging whether the vehicle exceeds the limiting speed.

A method and system may provide speed limit data to users driving in vehicles. A user's client device such as a smart-phone, smart watch, or tablet computer, may provide visual, audible, and/or haptic alerts to the user when the user exceeds a posted speed limit by more than a threshold amount. For example, when the user exceeds the posted speed limit by more than the threshold amount, the user's smart-phone may play a beeping sound and may announce the posted speed limit to the user. A map of a geographic area including the user's travelled route may also be displayed, with annotated areas along the route where the user exceeded the posted speed limit. The map may also include an indication of a proportion of a duration or distance of the route in which the user travelled above the posted speed limit.

A vehicle alert management system that manages alert lights and tones in accordance with vehicle speed and other inputs is described. The vehicle alert management system is configured so that in use the alert management system attenuates an alert lamp or click or tone after a selected time interval if the system detects that vehicle speed is below a selected speed or within a selected threshold, or if the system detects no change outside a threshold speed range, or other suitable speed algorithm. The system in embodiments is configured to attenuate the in-vehicle cabin sound associated with a direction indicator on a vehicle so that it is inhibited after a selected time period, and allowed to play in the cabin after the vehicle speed moves out of a selected threshold range.

A system and method in a building or vehicle for an actuator operation in response to a sensor according to a control logic, the system comprising a router or a gateway communicating with a device associated with the sensor and a device associated with the actuator over in-building or in-vehicle networks, and an external Internet-connected control server associated with the control logic implementing a PID closed linear control loop and communicating with the router over external network for controlling the in-building or in-vehicle phenomenon. The sensor may be a microphone or a camera, and the system may include voice or image processing as part of the control logic. A redundancy is used by using multiple sensors or actuators, or by using multiple data paths over the building or vehicle internal or external communication. The networks may be wired or wireless, and may be BAN, PAN, LAN, WAN, or home networks.

A displaying apparatus, includes a speed limit recognition unit configured to obtain a speed limit of a road on which the vehicle travels, and a speedometer display unit configured to display a visual bar varying according to a current speed of the vehicle on a background speed scale image and displaying a visual indicator for the speed limit at a corresponding position of the background speed scale image.

A shift control system for an industrial vehicle includes a vehicle speed monitor, a vehicle speed limit value setting section, a gear determination section, and a control section. The vehicle speed monitor is configured to monitor and detect an actual vehicle speed of the industrial vehicle. The vehicle speed limit value setting section is configured to set a vehicle speed limit value. The gear determination section is configured to select a transmission gear position of the transmission based on the actual vehicle speed and the vehicle speed limit value. The control section is configured to control the transmission in response to the selected transmission gear position. The gear determination section maintains the transmission in the currently-selected transmission gear position when the vehicle speed limit value is equal to or less than a predetermined threshold value and the threshold value is greater than an upshifting vehicle speed for upshifting the transmission.
