This toolkit is an automated, lab based tool useful to create, configure, present and evaluate the virtual environment providing scope for repeatable and realistic like in-lab testing of different road conditions and traffic simulations.Advanced driver-assistance system (ADAS),which is an electronic system that the driver to drive and park vehicle, can be developed with by using VTD toolkit. VTD can also be used for developing automated driving systems.
VTD provides scope to generate 3D content, simulate complex traffic scenario, and simulate simplified or physically driven sensors.
The data collected from the field is used to design road network and traffic simulations. Road networks are designed using Road Network Editor (ROD) which includes number of lanes, different types of intersections, traffic signs and signals.
ADAS is an electronic system beneficial from road safety point of view. It helps drivers to drive and park vehicles safely. It uses different electronic technologies like Micro controller units (MCU), Power semiconductor devices and electronic control units to avoid human errors and develop advanced driver assistance system. This technology helps in avoiding vehicle collisions and control road accidents.
Electric vehicles could be a better alternative to IC engine of fuel engine vehicles to reduce air pollution, but the government's aim is to replace all Fuel Vehicle to electric vehicles in the next decade, that clearly indicates that by 2030 goverment is aiming to make india 100% Electric Vehicle Country.In India, a particular set of circumstances which are conducive to a sustainablemobility paradigm have created an opportunity for accelerated adoption of EVs over ICE vehicles.
The functional model for electric drives and HV systems in vehicles consists of a drive module and an energy supply and control module. The HV system works with an operating voltage of 96 V. It includes a complete energy supply unit with an electronic battery management system (BMS), an integrated charger for the HV battery, a control unit with an engine management system, all of the necessary safety components, a Mennekes charging connection and an extra robust service disconnect. The HV battery, with a nominal voltage of 96 V, is equipped with 32 LiFePO4/40 Ah cells. The battery management system features a Bluetooth interface. A corresponding app (Android) can be used to display the condition (voltage, temperature, balancing rate during the charging process) of each individual battery cell.
The system comprises of three systems Drive Module, E-Car-Box & Battery Management System.
The drive module consists of a complete rear-axle powertrain with the gearbox from the Smart 450, 15 kW asynchronous motor, a control unit with controller (E-Car-Box), DC/DC converter, fuses, contactors and control software, and a hydraulic brake for load simulation (uphill driving).
The E-Car-Box is the core element of the drive. It houses all key components for actuating the motor in a space-saving, secure and EMC-compliant manner; these are cabled in accordance with the most stringent safety standards. In addition to the air-cooled Curtis controller for actuating the motor, it also contains the main contactor, a DC/DC converter and all necessary high- and low-voltage fuses.
3.Battery management system (BMS)
The battery management system monitors the lithium iron phosphate battery cells installed in the HV trainer and the extent to which they are protected against overvoltage and under voltage during the charging process and while driving. As such, the central control unit communicates with the connected charger and motor controller via CAN interface. The battery management system features a Bluetooth module for communication between the BMS and a display instrument such as a smartphone, tablet or Bluetooth-compatible Windows PC. Apps for Windows Mobile and Android are available for download. This module enables the state of charge of the batteries and various other parameters to be monitored.
