Vikas Motor Co. Kalbadevi, Mumbai, Maharashtra

The Electronic Control Unit is mounted on the vehicle in any preferred location in the drivers cabin. The unit receives pulses from the speed sensor based on which it computes the speed and distance and records the same with a help of a memory chip.Speed sensor is unique to the vehicle capable of being mounted on the gear box with easy installation and without lossmodification to any existing part. The Sensor generates pulses in relation to the speed of the vehicle. The mechanism has been designed to withstand hazardous and dusty, grimy and corrosive environment. There are no gears or mechanical drives to tamper with and change the ratios.

The Road Speed Limiter consists of an Electronic Control Unit, Speed Sensor, Motor Assembly and Spring Rod Assembly. The Speed Sensor generates electronic pulses in relation to the speed of the vehicle and transmits the same to the ECU. Bestowed with intelligence, the ECU computes the speed of the vehicle and continuously monitors the same. Whenever the vehicle reaches the maximum set speed, the ECU activates the motor assembly that controls the movement of the FIP Lever through the Spring Rod Assembly connected in between. By controlling the movement of the FIP Lever, the fuel flow is regulated and vehicle speed is governed.

The system monitors and displays critical operating parameters like Engine RPM, Coolant Temperature, Lube Oil Temperature, Lube Oil Pressure, Battery Voltage and Cumulative Engine Run Hours. All the abovementioned parameters except Cumulative Engine Run Hours and Lube Oil Temperature can be viewed both in analog and digital mode.

The Electronic Taxi Fare Meter displays the fare as per the prevalent RTA rules. It also displays the Waiting Time and the corresponding waiting fare as per the prevalent RTA rules. The unit also indicates date, total kilometers travelled (from the date of installation of the Taxi Fare Meter), total trip kilometers, total fare (all cumulative), total trips, daily total kilometers and daily total fare (all re-settable).The Front Panel of the unit features two displays, the Upper Digital Display to indicate Fare and the Lower Digital Display to indicate different function parameters. Three Self Illuminated Select Switches are provided to select the various modes of operation. A sticker indicating the Vehicle Registration Number is also provided.

The Electronic Auto Fare Meter Features: 1.Micro-controller based design to assure efficient and reliable performance. 2.Bright displays to enable easy readability in sunny and bright environment. 3.Incorporation of fare changes by authorized persons.

The System displays critical operating parameters like Engine RPM, Coolant Temperature, Oil Temperature, Oil Pressure, Battery Voltage and Cumulative Engine Running Hours. If a fault occurs the System indicates the nature of the fault and it gives a pre-alarm. If the same parameter attains the trip value, the system automatically provides an output signal that can be used to stop the diesel engine.
