SMARTBENCH

SMARTBENCH

Product Overview:
Smartbench Is a test/breakout box used to connect the Toughcase VCU to external IO and system buses. The Smartbench allows the connection of analog and digital inputs through Banana jacks. It allows CAN messages to be transferred over 2 built-in CAN buses. It drives Digital and PWM signals out to connected devices.

Smartbench comes with CAN Open-based 15 key keypads, and a 7" CAN open-based display. It supports 6 Digital connections with input switches and banana jacks. It has 6 Banana Jack Analog inputs that can be connected to devices such as an analog throttle peddle. It supports 16 digital/PWM outputs. These outputs can be fed through relays to control higher-power devices

The CAN Open keypad can be configured to transmit CAN messages to the Toughcase. The 7" display can be configured to display data received in CAN messages and transmit CAN messages when touchscreen controls are activated.

Product Specifications:
The Smartbench is designed to expose and allow the connection of all Toughcase signals for the user.
The Smartbench will:
• It will support connections for power and ground.
• It will have 6 digital input connections
• It will have 6 A to D channel connections
• It will have 16 Digital/PWM output connections
• It will contain three CAN busses (Only two CAN busses supported on non-CM4+ VCUs, Three CAN busses if the CM4+ module is used.)
Supplied Experiments:
1. Buzzer Beep: (A)
The Buzzer experiment beeps the Toughcase buzzer.
It is used to show initial connections and the minimum configuration needed. It introduces the Buzzer application.
The Buzzer Experiment will illustrate how to set up the Toughcase. Including Connecting it to power, peripherals, and the Toughcase. The experiment will explain how to physically connect the Toughcase to the user's computer using the flashing interface. (It could either use the CM+ modules Ethernet or the CAN bootloader to flash the module.)
It will introduce the Buzzer beep Simulink model. The model initializes the Toughcase's MCU and beeps the buzzer. The model configuration will highlight the basic configuration of the MCU.
The Simulink model will then be compiled. Flashing, debugging, and calibration of the module will be covered.
Calibration of the buzzer's beep rate can be done through Freemaster.
2. Digital Input and Output: (A)
Experiment Reads digital input and drives digital outputs. Explain High side vs. low side driver. Explain the wiring of all inputs and Outputs.
3. CAN Communications: (A)
The CAN Experiment builds on the foundation of the Buzzer experiment. The CAN experiment uses a model that begins by transmitting and receiving CAN data packets.
4. Display CANOpen Interface: (D)
The CAN Communications model is the base for this model. The CAN model is then enhanced to transmit and receive CAN open packets from the Display.
Initially, the display will use a prebuilt CAN Open configuration. The initial configuration will allow the display of system variables and the control of system devices. The initial configuration will display the ignition key state, PRNDL state, Throttle position, brake state, parking brake state, Derate state, Motor RPM, and simulated vehicle speed. The touchscreen display configuration will send CAN messages when PRNDL state is changed, and the Brake state is changed.
This experiment will show how to modify the display configuration.
5. Keypad CAN Open Interface: (D)
The CAN open keypad Can then be added to the Can Communication experiment. It sends CAN Open messages. In the initial CAN Open configuration, the keypad will send messages for the on/off, P, R, N, D, L, Adaptive cruise control, CC Set+, CC Set-, ACC headway, Lane-keeping, mode, steering wheel and Aux buttons,
6. Turn signal program:
Reads input switches, and drives blinking LED outputs. (D)
The turn signal experiment will allow the reading of control switches to turn on the right left and hazard lights. The lights will blink based on a timer in the turn signal model.

7. Analog to Digital Conversion: (A)
Read Analog to digital converter, Transfer read data to CAN bus.

8. Throttle response Experiment: (Current test bench program) (D)
The throttle response Experiment will be a summation of all the previous experiments. The User will use the throttle to drive a motor. It will use the display and keypad. It will use digital inputs and either CAN or digital outputs to drive the motor.
The program reads the throttle position. The throttle position is shown on display and CAN communications. VCU sends a throttle CAN message to the inverter. The inverter drives the electric motor.
The user will power on the system. They will flash in the throttle response program. They will then "start" the system by pressing the start button on the keypad. The motor system should power up in neutral at this point. The user will press the brake button on the keypad. The user will then press the forward button. The motor should speed up based on the throttle pedal input. The user should then select Neutral. The motor should stop. The user can then select reverse. The motor will run at lower speeds in reverse.

9. Motor Control
In this experiment, we explore the Motor Control capabilities of the Dorleco VCU using a throttle pedal as throttle input and F, N, and R buttons on the display. It should be able to control both BLDC/PMSM (speed control) and Servo motors (position control). You will be able to control the motor's speed/position using the throttle pedal and the display.
10. Use VCU as a BMS
In this experiment, we explore the ability of the VCU to be used as a supervisory BMS. It uses the data from the analog pins or an AFE to manage various parameters of the battery thus maintaining its health. Features like cell balancing, SOC estimation, and Charge/discharge are implemented.
11. Brake by Wire
In this experiment, we use software controls to apply the brakes on a vehicle using the VCU. The VCU will use various internal and external controls to reduce the speed of the vehicle. The brakes can be applied by processing sensor data like radar or proximity, or other inputs received externally over CAN.
12. Speedometer (motor speed and rpm values extraction)
In this experiment, we use hall sensors positioned on the motor to calculate the speed (RPM) of the motor. It also includes a motor throttle control system using a throttle pedal. It requires a motor with hall sensors, a motor controller, and a throttle pedal.
13. Cruise Control
In this experiment, we will be implementing a cruise control system. The VCU will measure and maintain a speed on the motor so that the driver can have a more relaxed drive. It is activated by pressing the CC button and can be disabled by pressing the button again, using sensor data like radar, braking, or pushing the throttle pedal further.
